The obtained C-TiO2 were used as catalytic supports to load Pd nanoparticles for H2 O2 direct synthesis from H2 and O2. The as-prepared samples were systematically studied by transmission electron microscopy(TEM), X-ray photoelectron spectroscopy(XPS), air isothermal microcalorimeter, temperature-programmed reduction of H2(H2-TPR), and so on. The catalytic results showed that H2 O2 productivity and H2O2 selectivity of Pd/C-TiO2 firstly rose with increasing carbon content and then declined. Pd/C-TiO2 catalyst with 1.89 wt% of carbon content showed the best catalytic performance that had 61.2% of selectivity and 2192 mmol H2O2/g Pd/h of productivity, which were significantly better than those of pristine Pd/TiO2(45.2% and 1827 mmol H2O2/g Pd/h). Various characterization results displayed that the carbon species were heterogeneously dispersed on TiO2 surface. Moreover, no obvious geometric transformation in supports and Pd nanoparticles were observed among different catalysts. The superficial hydrophobicity of Pd/C-TiO2 was gradually promoted with increasing carbon content, which led to the corresponding decrease in adsorption energy of H2O2 with catalysts. According to structure-performance relationship analyses, the heterogeneous interfacial engineering of carbon could maintain the interaction of Pd nanoparticles with TiO2 and simultaneously accelerate the H2O2 desorption. Both factors further determined the excellent H2O2 direct synthesis performance of Pd/C-TiO2.展开更多

One efficiencylimiting factor is the improper contacts between the halide double perovskite and anode/cathode electrodes. Here, we improve the efficiency and stability of the bismuth-halide double perovskite based solar cells by a synergistic interface design for both electron and hole transport layers(ETL/HTL). The results show that the modification of the TiO_2 ETL with a thin hydrophobic C60 layer and replacement of the lithium-doped small molecule HTL with an un-doped conjugated polymer lead to higher surface quality of perovskite film and better energy-level alignment at the contacts. As a result, the optimized device shows reduced trap density, suppressed charge recombination and enhanced charge extraction, leading to an increase of 69% in device efficiency. In addition, the device also exhibits superior stability in ambient environment, heat stress and light bias after interface optimization. This work provides an efficient strategy for the device optimization of the emerging lead-free perovskite solar cells.展开更多

The size and morphology of the catalysts are significantly changed after the CoS_(2) is grown on ReS_(2), providing regulation of the catalytic activity of ReS_(2). Particularly, the optimized CoS_(2)-ReS_(2) shows superior electrocatalytic properties with a low voltage of 1.48 V at 20 mA cm^(-2) for overall water splitting in 1.0 M KOH, which is smaller than the noble metal-based catalysts(1.77 V at 20 mA cm^(-2)). The XPS, XAS, and theoretical data confirm that the interfacial regulation of ReS_(2) by CoS_(2) can provide rich edge catalytic sites, which greatly optimizes the catalytic kinetics and drop the energy barrier for oxygen/hydrogen evolution reactions. Our results demonstrated that interfacial engineering is an efficient route for fabricating high-performance water splitting electrocatalysts.展开更多

In this review, the research status and related interface engineering strategies of Mn-based oxide cathode electrode materials for ZIB in recent years are summarized. Specifically, the review will focus on three types of interface engineering strategies, including interface reconstruction via cathode, interface reconstruction electrolyte, and protection via artificial cathode-electrolyte interphase(CEI) layer, within the context of their evolution of interface layer and corresponding electrochemical performance. A series of experimental variables, such as crystal structure, electrochemical reaction mechanism, and the necessary connection for the formation and evolution of interface layer, will be carefully analyzed by combining various advanced characterization techniques and theoretical calculations. Finally, suggestions and strategies are provided for reasonably designing the cathode-electrolyte interface to realize the excellent performance of Mn-based oxide zinc-based batteries.

文摘Aqueous zinc ion batteries(AZIBs)are promising energy storage devices.However,the formation of dendrites,hydrogen evolution,and corrosion reaction seriously affect their electrochemical performance.Herein,the synergistic effect of ion-migration regulation and interfacial engineering has been confirmed as the potential strategy by kaolin functionalized glass fiber separator(KL-GF)to alleviate these problems.The rapid and orderly Zn^(2+)migration was achieved to improve the transfer kinetics and induced uniform zinc deposition by more zinc-philic sites of KL-GF.Based on the interfacial engineering,the side reactions were effectively mitigated and crystal planes were regulated through KL-GF.The hydrophilicity of KL alleviated the corrosion and hydrogen evolution.Importantly,a preferential orientation of Zn(002)crystal plane by KL-GF was induced to further realize dendrite-free deposition by density functional theory(DFT)and X-ray diffraction(XRD)characterization.Hence,the Zn|KL-GF|MnO_(2)cell maintained a high discharge capacity of 96.8 mAh/g at 2 A/g after 1000 cycles.This work can provide guidance enabling high-performance zinc anode for AZIBs.

文摘Mixing two or more polymers to produce the“polymer alloy”is one of the most versatile and economical strategies for developing new polymeric materials.The compatibility between polymer components largely determines the comprehensive performance of polymer blend.More recently,a type of unique surface partitioned materials,Janus particles,has been proposed to act as a novel interfacial compatibilizer for polymer blends.Such Janus particles integrates the amphipathicity of diblock copolymer and interfacial stabilization of nanoparticles,displaying a significant superiority in comparison with molecular compatibilizers for a wide range of polymer blends.In this review,we mainly focus on the compatibilizing effects of Janus nanofillers of various morphologies,including spherical,snowman-like,and two-dimensional nanosheets,on polymer blends.We shed light on the impacts of compatibilization of Janus particles on phase morphologies,mechanical properties,and functionalities of polymer blends.This review could provide a guidance for designing an effective Janus particle compatibilizer to develop high-performance polymer blends.

文摘The interfacial enhanced ferromagnetism in maganite/ruthenate system is regarded as a promising path to broaden the potential of oxide-based electronic device applications.Here,we systematically studied the physical properties of La_(1-x)Ca_(x)MnO_(3)/SrRuO_(3)superlattices and compared them with the La1-x Cax MnO_(3)thin films and bulk compounds.The La_(1-x)Ca_(x)MnO_(3)/SrRuO_(3)superlattices exhibit significant enhancement of Curie temperature(TC)beyond the corresponding thin films and bulks.Based on these results,we constructed an extended phase diagram of La_(1-x)Ca_(x)MnO_(3)under interfacial engineering.We considered the interfacial charge transfer and structural proximity effects as the origin of the interfaceinduced high TC.The structural characterizations revealed a pronounced increase of B-O-B bond angle,which could be the main driving force for the high TCin the superlattices.Our work inspires a deeper understanding of the collective effects of interfacial charge transfer and structural proximity on the physical properties of oxide heterostructures.

文摘High-specific-energy batteries with long-lifespan are the development aspiration for energy storage applications.Metal electrodes with high specific capacity and low reduction potential are potential candidates for next-generation high-specific-energy batteries.Nevertheless,the stability of the metal electrode batteries is constantly suffered from the unstable interface issue during the plat-ing/stripping process,such as dendrite formation,dynamic evolution of solid electrolyte interphase,and other accompanied side reactions.To solve these challenges,numerous researches have been intensively studied based on the interfacial engineering of metal electrodes,including electrode configuration optimization,interfacial chemistry regulation and solid-solid interface construc-tion,and the recent progress is elaborately introduced in this paper.Nevertheless,the dendrite issues cannot be entirely prohibited in solid metal electrodes,which motivate the search for potential alternatives.Liquid-metal electrodes with completely reversible structural changes and high mass transfer rate are rendered as an effective approach to solve the dendrite problem.Therefore,the development of liquid metal electrode batteries is reviewed in this paper,in which the interfacial issues are explicated and some commendable achievements are summarized.In the end,the implementation of interfacial engineering and the development roadmap of the metal electrode batteries are prospected.

文摘Urea-assisted natural seawater electrolysis is an emerging technology that is effective for grid-scale carbon-neutral hydrogen mass production yet challenging.Circumventing scaling relations is an effective strategy to break through the bottleneck of natural seawater splitting.Herein,by DFT calculation,we demonstrated that the interface boundaries between Ni_(2)P and MoO_(2) play an essential role in the selfrelaxation of the Ni-O interfacial bond,effectively modulating a coordination number of intermediates to control independently their adsorption-free energy,thus circumventing the adsorption-energy scaling relation.Following this conceptual model,a well-defined 3D F-doped Ni_(2)P-MoO_(2) heterostructure microrod array was rationally designed via an interfacial engineering strategy toward urea-assisted natural seawater electrolysis.As a result,the F-Ni_(2)P-MoO_(2) exhibits eminently active and durable bifunctional catalysts for both HER and OER in acid,alkaline,and alkaline sea water-based electrolytes.By in-situ analysis,we found that a thin amorphous layer of NiOOH,which is evolved from the Ni_(2)P during anodic reaction,is real catalytic active sites for the OER and UOR processes.Remarkable,such electrode-assembled urea-assisted natural seawater electrolyzer requires low voltages of 1.29 and 1.75 V to drive 10 and600 mA cm^(-2)and demonstrates superior durability by operating continuously for 100 h at 100 mA cm^(-2),beyond commercial Pt/C||RuO_(2) and most previous reports.

文摘Lead(Pb)-free Tin(Sn)-based perovskite solar cells(PSCs)have been favored by the community due to their low toxicity,preferable bandgaps,and great potential to achieve high power conversion efficiencies(PCEs).Interfaces engineering plays important roles in developing highly efficient Sn-based PSCs via passivation of trap defects,alignment of energy levels,and incorporation of low-dimensional Sn-based perovskites.In this review,we summarize the development of Pb-free Sn-based perovskites and their applications in devices,especially the strategies of improving the interfaces.We also provide perspectives for future research.Our aim is to help the development of new and advanced approaches to achieving high-performance environment-friendly Pb-free Sn-based PSCs.

文摘Herein, a stable and efficient CoS_(2)-ReS_(2) electrocatalyst is successfully constructed by using the different molar ratios of CoS_(2) on ReS_(2). The size and morphology of the catalysts are significantly changed after the CoS_(2) is grown on ReS_(2), providing regulation of the catalytic activity of ReS_(2). Particularly, the optimized CoS_(2)-ReS_(2) shows superior electrocatalytic properties with a low voltage of 1.48 V at 20 mA cm^(-2) for overall water splitting in 1.0 M KOH, which is smaller than the noble metal-based catalysts(1.77 V at 20 mA cm^(-2)). The XPS, XAS, and theoretical data confirm that the interfacial regulation of ReS_(2) by CoS_(2) can provide rich edge catalytic sites, which greatly optimizes the catalytic kinetics and drop the energy barrier for oxygen/hydrogen evolution reactions. Our results demonstrated that interfacial engineering is an efficient route for fabricating high-performance water splitting electrocatalysts.

文摘Through strategies such as process optimization,solvent selection,and component tuning,the crystallization of perovskite materials has been effectively controlled,enabling perovskite solar cells(PSCs)to achieve over 25%power conversion efficiency(PCE).However,as PCE continues to improve,interfacial issues within the devices have emerged as critical bottlenecks,hindering further performance enhancements.Recently,interfacial engineering has driven transformative progress,pushing PCEs to nearly 27%.Building upon these developments,this review first summarizes the pivotal role of interfacial modifications in elevating device performance and then,as a starting point,provides a comprehensive overview of recent advancements in normal,inverted,and tandem structure devices.Finally,based on the current progress of PSCs,preliminary perspectives on future directions are presented.

文摘Developing renewable hydrogen technologies requires high-efficiency pH-universal hydrogen evolution reaction(HER)electrocatalysts.Ruthenium phosphides(RuPx)have great potentials to replace the commercial Pt-based materials,whereas the optimization of their electronic structure for favorable reaction intermediate adsorption remains a significant challenge.Herein,we report an innovative phosphorization-controlled strategy for the in-situ immobilization of core/satellite-structured RuP/RuP_(2)heteronanoparticles onto N,P co-doped porous carbon nanosheets(abbreviated as RuP/RuP_(2)@N/P-CNSs hereafter).Density functional theory(DFT)calculations further reveal that the electron shuttling at the RuP/RuP_(2)interface leads to a reduced energy barrier for H2O dissociation by electron-deficient Ru atoms in the RuP and the optimized H*adsorption of electron-gaining Ru atoms in the RuP_(2).Impressively,the as-synthesized RuP/RuP_(2)@N/P-CNSs exhibits low overpotentials of 8,29,and 66 mV to achieve 10 mA cm^(-2)in alkaline,acid and neutral media electrolyte,respectively.This research presents a viable approach to synthesize high-efficiency transition metal phosphide-based electrocatalysts and offers a deeper comprehension of interface effects for HER catalysis.

文摘Electrochemical nitrate reduction reaction(NITRR)has emerged as a promising approach for both nitrate contamination removal and ammonia producing in mild ambient conditions.Herein,a novel strategy based on interfacial engineering is proposed to improve the catalytic performance of MoS_(2)via introducing few-layer V_(2)C MXene heterostructure.This explicitly tailored method effectively addresses the challenge of MoS_(2)aggregation,while simultaneously inducing transformative changes in the native electron orbitals of Mo active sites in MoS_(2).The optimal heterostructure MoS_(2)@V_(2)C catalyst emerges with excellent attributes:nitrate removal rate(93%),ammonia selectivity(84%),and Faradic efficiency(80%)at-0.9 V(vs.reversible hydrogen electrode(RHE))in a low NO_(3)^(-)concentration.The theoretical research demonstrates the energy barrier of ^(*)NO to ^(*)NOH is significantly reduced by 0.92 eV after inducing V_(2)C MXene.Moreover,there is an evident shift in the center of the d-band towards the Fermi level,accompanied by a potent suppression of the hydrogen evolution reaction.

文摘The rapid proliferation of microelectronics,coupled with the advent of the internet ofthings(IoT)era,has created an urgent demand for miniaturized,integrable,and reliable on-chip energystorage systems.All-solid-state thin-film microbatteries(TFMBs),distinguished by their intrinsicsafety,compact design,and compatibility with microfabrication techniques,have emerged as promisingcandidates to power next-generation IoT devices.Nevertheless,in contrast to the well-establisheddevelopment of conventional lithium-ion batteries,the advancement of TFMBs remains at an earlystage,facing persistent challenges in materials innovation,interface optimization,and scalable manufacturing.This review critically examines the pivotal role of vapor deposition technologies,includingmagnetron sputtering,pulsed laser deposition,thermal/electron-beam evaporation,chemical vapordeposition,and atomic layer deposition,in the fabrication and performance modulation of TFMBs.We systematically summarize recent progress in thin-film electrodes and solid-state electrolytes,withparticular emphasis on how deposition parameters dictate crystallinity,lattice orientation,and ionictransport in functional layers.Furthermore,we highlight strategies for solid-solid interface engineering,three-dimensional structural design,andmultifunctional integration to enhance capacity retention,cycling stability,and interfacial compatibility.Looking ahead,TFMBs are expectedto evolve toward multifunctional platforms,exhibiting mechanical flexibility,optical transparency,and hybrid energy-harvesting compatibility,thereby meeting the heterogeneous energy requirements of future IoT ecosystems.Overall,this review provides a comprehensive perspective onvapor-phase-enabled TFMB technologies,delivering both theoretical insights and technological guidelines for the scalable realization of highperformancemicroscale power sources.
