In this study, a vacuum-assisted filtration process was employed to fabricate ammoniated alumina/MXene/bacterial cellulose (Al_(2)O_(3)-NH_(2)/MXene/BC) composite films that display a unique integration of properties, encompassing ultra-high thermal conductivity (λ), mechanical flexibility, and high photothermal conversion performance. By leveraging the bridging effect among spherical Al_(2)O_(3)-NH_(2) and MXene nanosheets, a densely packed “point-surface” structure was constructed in BC by using a one-step preparation process. When the mass fraction of Al_(2)O_(3)-NH_(2)/MXene (1:3, w/w) is 40 wt%, the O-BAl1M3 exhibited an in-plane λ of 20.02 W m^(-1) K^(-1), which was 436 % and 94 % higher than that of pure BC and T-BAl1M3 (prepared by a two-step method), respectively. Furthermore, constructing an intact thermal conductive network within BC notably promoted photothermal and photoelectric conversion performance. The maximum surface temperature and voltage of the O-BAl1M3 film reached 106.9 ℃ and 48.34 mV when a sample with an area of 1.56 cm^(2) was exposed under a light intensity of 200 mW cm^(-2). By applying O-BAl1M3 film, the temperature inside a self-built greenhouse model reached up to 64.8 ℃ within 1200 s under a light intensity of 100 mW cm^(-2), which validated the practical application of the composite films and offered a novel approach for creating flexible films with superior photothermal conversion capability. This work provided insights into preparing functional composite films for efficient thermal management and photothermal conversion applications.展开更多

文摘Photoheranostics have emerged as a promising tool for cancer theranostics owing to their real-time feedback on treatment and their precise diagnosis.Among them,how to improve the photothermal conversion efficiency(PCE)of phototheranostic agents(PTAs)is the key factor for phototheranostic systems.Herein,we provided an efficient method to improve PCE and constructed a biocompatible nano-material ICR-Qu@NH_(2)-Fe_(3)O_(4)@PEG(QNFP)by combing near-infrared second region(NIR-Ⅱ)molecular dye ICR-Qu and amino-modified magnetic nanoparticles and then encapsulated by DSPE-m PEG2000.QNFP exhibited excellent performance for photothermal therapy with a high PCE of 95.6%.Both in vitro and in vivo experiments indicated that QNFP could inhibit the growth of tumors under laser irradiation with low toxicity and realized real-time NIR-Ⅱfiuorescent imaging of tumors.In general,we realized a simple but efficient method to improve the PCE of NIR-Ⅱmolecular dye without reduce its quantum yield,which is an ideal choice for cancer diagnosis and treatment.

文摘Multidimensional confined structure systems are proposed and demonstrated by using MoO_(2)@MO_(2)C(MMC)to enhance the photothermal catalytic performance of the metal sulfides-multidimensional confined structure(TMs-MDCS).Specifically,the MMC nanoparticles confined to the surface of the ZnIn_(2)S_(4)hollow tube-shell(MMC/HT-ZIS)achieve a hydrogen evolution rate of 9.72 mmol g^(-1)h^(-1),which is 11.2 times higher than that of pure HT-ZIS.Meanwhile,the MnCdS(MCS)nanoparticles are encapsulated within the two-dimensional MMC(2D MMC/MCS)through precise regulation of size and morphology.The 10-MMC/MCS lamellar network demonstrates the highest hydrogen evolution rate of 8.19 mmol g^(-1)-h^(-1).The obtained MMC/TMs-MDCS catalysts exhibit an enhanced photocatalytic hydrogen evolution rate,which can be attributed to the strong synergistic interaction between the multidimensional confinement and the photothermal effects.The confinement space and the strong interfacial relationship within the MMC/TMs-MDCS create abundant channels and active sites that facilitate electron migration and transport.Furthermore,the construction of a confined environment positions these materials as promising candidates for achieving exceptional photothermal catalytic performance,as MMC/TMs-MDCS enhance light absorption through light scattering and reflecting effects.Additionally,the capacity of MMC/TMsMDCS to convert solar light into thermal energy significantly reduces the activation energy of the reaction,thereby facilitating reaction kinetics and accelerating the separation and transport of photogenerated carriers.This work provides valuable insights for the development of highly efficient photothermal catalytic water-splitting systems for hydrogen production using multidimensional confined catalysts.

文摘The utilization of solar-driven interfacial evaporation technology is highly important in addressing the energy crisis and water scarcity,primarily because of its affordability and minimal energy usage.Enhancing the performance of solar energy evaporation and minimizing material degradation during application can be achieved through the design of novel photothermal materials.In solar interfacial evaporation,photothermal materials exhibit a wide range of additional characteristics,but a systematic overview is lacking.This paper encompasses an examination of various categories and principles pertaining to photothermal materials,as well as the structural design considerations for salt-resistant materials.Additionally,we discuss the versatile uses of this appealing technology in different sectors related to energy and the environment.Furthermore,potential solutions to enhance the durability of photothermal materials are also highlighted,such as the rational design of micro/nano-structures,the use of adhesives,the addition of anti-corrosion coatings,and the preparation of self-healing surfaces.The objective of this review is to offer a viable resolution for the logical creation of high-performance photothermal substances,presenting a guide for the forthcoming advancement of solar evaporation technology.
文摘CeO_(2) based semiconductor are widely used in solar-driven photothermal catalytic dry reforming of methane(DRM)reaction,but still suffer from low activity and low light utilization efficiency.This study developed graphite-CeO_(2) interfaces to enhance solar-driven photothermal catalytic DRM.Compared with carbon nanotubes-modified CeO_(2)(CeO_(2)-CNT),graphite-modified CeO_(2)(CeO_(2)-GRA)constructed graphite-CeO_(2) interfaces with distortion in CeO_(2),leading to the formation abundant oxygen vacancies.These graphite-CeO_(2) interfaces with oxygen vacancies enhanced optical absorption and promoted the generation and separation of photogenerated carriers.The high endothermic capacity of graphite elevated the catalyst surface temperature from 592.1−691.3℃,boosting light-to-thermal conversion.The synergy between photogenerated carriers and localized heat enabled Ni/CeO_(2)-GRA to achieve a CO production rate of 9985.6 mmol/(g·h)(vs 7192.4 mmol/(g·h)for Ni/CeO_(2))and a light-to-fuel efficiency of 21.8%(vs 13.8%for Ni/CeO_(2)).This work provides insights for designing graphite-semiconductor interfaces to advance photothermal catalytic efficiency.

文摘The full arrival of 5 G and advances in electronic integration make efficient heat dissipation crucial for stable operation and longer product lifespan. In this study, a vacuum-assisted filtration process was employed to fabricate ammoniated alumina/MXene/bacterial cellulose (Al_(2)O_(3)-NH_(2)/MXene/BC) composite films that display a unique integration of properties, encompassing ultra-high thermal conductivity (λ), mechanical flexibility, and high photothermal conversion performance. By leveraging the bridging effect among spherical Al_(2)O_(3)-NH_(2) and MXene nanosheets, a densely packed “point-surface” structure was constructed in BC by using a one-step preparation process. When the mass fraction of Al_(2)O_(3)-NH_(2)/MXene (1:3, w/w) is 40 wt%, the O-BAl1M3 exhibited an in-plane λ of 20.02 W m^(-1) K^(-1), which was 436 % and 94 % higher than that of pure BC and T-BAl1M3 (prepared by a two-step method), respectively. Furthermore, constructing an intact thermal conductive network within BC notably promoted photothermal and photoelectric conversion performance. The maximum surface temperature and voltage of the O-BAl1M3 film reached 106.9 ℃ and 48.34 mV when a sample with an area of 1.56 cm^(2) was exposed under a light intensity of 200 mW cm^(-2). By applying O-BAl1M3 film, the temperature inside a self-built greenhouse model reached up to 64.8 ℃ within 1200 s under a light intensity of 100 mW cm^(-2), which validated the practical application of the composite films and offered a novel approach for creating flexible films with superior photothermal conversion capability. This work provided insights into preparing functional composite films for efficient thermal management and photothermal conversion applications.

文摘Radical anions of electron-deficient perylene diimides(PDI)are attractive near-infrared(NIR)absorbers for photothermal conversion;however,their stability is often compromised by strong aggregation and reoxidation in air.Herein,we present a class of bacterial composites hybridized with a newly synthesized doubly-strapped PDI cyclophane,termed“Gemini Box”(GBox-3^(4+)),which features air-stable PDI radicals for NIR photothermal conversion.The effective spatial isolation provided by the double-sided cationic molecular straps allows GBox-3^(4+)to completely suppress chromophore aggregation,even in concentrated aqueous solutions up to 2 mmol/L,thereby preserving its characteristic fluorescence for live-cell imaging.After incubation of bacteria with GBox-3^(4+),the radical species PDI·-have been found to stably exist in the bacterial composites under ambient conditions,both in aqueous suspension and solid forms.Further experiments demonstrate that the air stability of the radical species relies on the simultaneous presence of the doubly-strapped PDI dye and the bacteria.Moreover,the dye-bacterial composites exhibited an high-efficiency NIR photothermal effect with high durability,enabling their application as photothermal agents for seawater desalination.This work provides a new access to the in situ fabrication of photothermal materials from biomass,relying on the rational molecular design and the unique microenvironment of bacteria.

文摘Photocatalysis(PC)and photoelectrocatalysis(PEC)represent promising and efficient avenues for harnessing solar energy to produce sustainable clean energy products and environmental remediation.Yet the current reaction efficiencies remain inadequate,limiting their efficiencies for practice.Despite the growing interest in photo thermal-driven PC/PEC systems,there is no comprehensive review that systematically summarises the role of the photothermal effect in bridging the gap between PC and PEC efficiencies.This review initially introduces the fundamental principles of PC and PEC,alongside the primary photothermal materials and relevant conversion mechanisms.Subsequently,the key influences of photothermal effects on PC and PEC performance(e.g.,light absorption,charge separation and transport,and surface reactions)and optimization strategies are discussed.In addition,the latest advancements in solar photothermal conversion are discussed,mainly focused on the widely application of different types of photothermal drive PC and PEC applications,such as PC and PEC oxygen evolution reaction(OER),hydrogen evolution reaction(HER),CO_(2)reduction reaction(CO_(2)RR),pollutant degradation,and sterilization,serving to illustrate the widespread applicability of the photothermal conversion.Finally,the development prospects and challenges of photothermal-assisted PC and PEC are discussed from the perspective of basic research and practical application.This work provides a timely and systematic framework to guide the rational design of photothermal-enhanced PC/PEC systems for sustainable energy and environmental applications.

文摘Low-cost and biodegradable photothermal wound dressings with remarkable therapeutic effects are highly desirable for next-generation wound healing.Herein,we report an efficient photothermal wound dressing mat made of tellurium nanosheet(TeNS)-loaded electrospun polycaprolactone/gelatin(PCL/GEL)nanofibers.The TeNS-loaded PCL/GEL nanofibrous architectures showed antibacterial efficacy against Escherichia coli and Staphylococcus aureus of 87.68%and 94.57%,respectively.Under near-infrared+(NIR)light illumination,they can facilitate cell proliferation as revealed by in vitro scratch assay.The results from in vivo skin wounds combined with tissue staining experiments further showed that the TeNS-loaded dressing could substantially promote wound healing under photothermal conditions.Using immunohistochemical analysis,we found that the TeNS-loaded PCL/GEL nanofibers NIR group have a high expression of specific antigens in epidermal growth factor(EGF)(P<0.001)and endothelial cell adhesion molecule-31(CD31,P<0.05),verifying that the nanofibrous mat can stimulate EGF generation and microvessel proliferation.Furthermore,the PCL/GEL/TeNIR group has the lowest expression in endothelial cell adhesion molecule-68(CD68,P<0.001),suggesting that the nanofibrous mats have a high anti-inflammatory efficiency.Our work sheds light on the development of novel nonanti-inflammatory wound dressings via photothermal sterilization and the promotion of cell growth using two-dimensional(2D)nanosheets.

文摘Tantalum nitride is widely considered as a promising photoanode material for its suitable band structure as well as the high theoretical conversion efficiency in solar water splitting.However,it is limited to inefficient photoinduced electron–hole pair separation and interfacial dynamics in the photoelectrochemical oxygen evolution reaction.Herein,multiple layers including Ti_(x)Si_(y) and NiFeCoO_(x) were fabricated based on band engineering to regulate tandem electric states for efficient transfer of energy carriers.Besides,photothermal local surface plasmon resonance was introduced to accelerate the kinetics of photoelectrochemical reactions at the interface when the special Ag nanoparticles were loaded to extend the absorbance to near infrared light.Consequently,a recordable photocurrent density of 12.73 mA cm^(-2) has been achieved at 1.23 V versus RHE,approaching a theoretical limit of the tantalum nitride photoanode with full-spectrum solar utilization.Meanwhile,compared to the applied bias photon-to-current efficiency of 1.36%without photothermal factor,a high applied bias photonto-current efficiency of 2.27%could be raised by applying local surface plasmon resonance to photoelectrochemical oxygen evolution reaction.The efficient design could maximize the use of solar light via the classification of spectrum and,therefore,may spark more innovative ideas for the future design and development of the next-generation photoelectrode.

文摘Integrating multiple modalities of cancer therapies for synergistic and enhanced therapeutic efficacy remains challenging.Herein,flash nanoprecipitation(FNP),a kinetically driven process,was employed to expedite the coordination reaction time required for nano-encapsulate components with completely opposite physiochemical properties including sorafenib(SRF),hemoglobin(Hb),chlorin e6(Ce6),and indocyanine green(ICG)into a multi-component HSCI nanomedicine.Hydrophilic components Hb and ICG interact to form hydrophobic ICG-Hb complexes under electrostatic and hydrophobic interactions.This process facilitates the characteristic time of nucleation(τ_(nucleation))to match the characteristic mixing time(τ_(mix))of the FNP process,resulting in the formulation of kinetically stable nanomedicine,overcoming the long equilibrium times and instability issues associated with thermodynamic assembly.Importantly,pH-responsive structure is also easily but effectively integrated in nanomedicine during this kinetically driven formulation to manipulate its structures.In the acidic tumor microenvironment(TME),the pH-stimulated morphology transformation of HSCI nanomedicine boosts its reactive oxygen species(ROS)generation efficiency and photothermal efficacy,endowing it with better antitumor suppression.In vitro and in vivo experiments reveal that the HSCI nanomedicine offers a synergistic therapeutic effect and stronger tumor suppression compared with single therapies.These results open a new window for developing strategies for multimodal combinatory cancer therapies.

文摘The previous studies mainly focused on improving microwave absorbing(MA)performances of MA materials.Even so,these designed MA materials were very difficult to be employed in complex and changing environments owing to their single-functionalities.Herein,a combined Prussian blue analogues derived and catalytical chemical vapor deposition strategy was proposed to produce hierarchical cubic sea urchin-like yolk–shell CoNi@Ndoped carbon(NC)-CoNi@carbon nanotubes(CNTs)mixed-dimensional multicomponent nanocomposites(MCNCs),which were composed of zerodimensional CoNi nanoparticles,three-dimensional NC nanocubes and onedimensional CNTs.Because of good impedance matching and attenuation characteristics,the designed CoNi@NC-CoNi@CNTs mixed-dimensional MCNCs exhibited excellent MA performances,which achieved a minimum reflection loss(RL_(min))of−71.70 dB at 2.78 mm and Radar Cross section value of−53.23 dB m^(2).More importantly,the acquired results demonstrated that CoNi@NC-CoNi@CNTs MCNCs presented excellent photothermal,antimicrobial and anti-corrosion properties owing to their hierarchical cubic sea urchin-like yolk–shell structure,highlighting their potential multifunctional applications.It could be seen that this finding not only presented a generalizable route to produce hierarchical cubic sea urchin-like yolk–shell magnetic NC-CNTs-based mixed-dimensional MCNCs,but also provided an effective strategy to develop multifunctional MCNCs and improve their environmental adaptabilities.

文摘Smart windows(SWs)garner significant potential in green buildings owing to their capability of on-demand tuning the solar gains.Apart from solar regulation,people always desire a type of slippery SW which can repel the surface hydrous contaminants for anti-fouling application.Unfortunately,the up-to-date slippery SWs that respond to electrical/thermal stimuli have drawbacks of inferior durability and high energy-consumption,which greatly constrain their practical usability.This article presents our current work on an ultra-robust and energy-efficient near-infrared-responsive smart window(NIR-SW)which can regulate the optical transmittance and droplet’s adhesion in synergy.Significantly,laser-printing strategy enables us to seed the shape-memory photothermal microwalls on a transparent substrate,which can promote daylighting while maintaining privacy by near-infrared(NIR)switching between being transparent and opaque.As a light manipulator,it turns transparent with NIR-activated erect microwalls like an open louver;however,it turns opaque with the pressure-fixed bent microwalls akin to a closed louver.Simultaneously,the droplets can easily slip on the surface of erect microwalls similar to a classical lotus effect;by contrast,the droplets will tightly pin on the surface of bent microwalls analogous to the prevalent rose effect.Owing to shape-memory effect,this optical/wettability regulation is thus reversible and reconfigurable in response to the alternate NIR/pressure trigger.Moreover,NIR-SW unfolds a superior longevity despite suffering from the raindrop’s impacting more than 10000 cycles.Remarkably,such a new-type SW is competent for thermal management,anti-icing system,peep-proof screen,and programmable optics.This work renders impetus for the researchers striving for self-cleaning intelligent windows,energy-efficient greenhouse,and so forth.
