The large-scale use of ample marine energy will be one of the most important ways for human to achieve sustainable development through carbon neutral development plans.As a burgeoning technological method for electromechanical conversion,triboelectric nanogenerator(TENG)has significant advantages in marine energy for its low weight,cost-effectiveness,and high efficiency in low-frequency range.It can realize the efficient and economical harvesting of low-frequency blue energy by constructing the floating marine energy harvesting TENG.This paper firstly introduces the power transfer process and structural composition of TENG for marine energy harvesting in detail.In addition,the latest research works of TENG on marine energy harvesting in basic research and structural design are systematically reviewed by category.Finally,the advanced research progress in the power take-off types and engineering study of TENG with the marine energy are comprehensively generalized.Importantly,the challenges and problems faced by TENG in marine energy and in situ electrochemical application are summarized and the corresponding prospects and suggestions are proposed for the subsequent development direction and prospects to look forward to promoting the commercialization process of this field. 展开更多

Electrocatalytic nitrate reduction reaction (NO_(3)-RR) to ammonia under ambient conditions is expected to be a green process for ammonia synthesis and alleviate water pollution issues.We report a CuO nanoparticles incorporated on nitrogen-doped porous carbon (CuO@NC) catalyst for NO_(3)-RR.Part of Cu(Ⅱ) is reduced to Cu(Ⅰ) during the NO_(3)-RR process to construct Cu(Ⅰ)-Cu(Ⅱ) pairs,confirmed by in situ X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy.Density functional theory (DFT) calculations indicated that the formation of Cu(Ⅰ) could provide a reaction path with smaller energy barrier for NO_(3)-RR,while Cu(Ⅱ) effectively suppressed the competition of hydrogen evolution reaction (HER).As a result,CuO@NC catalyst achieved a Faradaic efficiency of 84.2% at -0.49 V versus reversible hydrogen electrode (RHE),and a NH_(3)yield rate of 17.2 mg h^(-1)mg^(-1)cat.at -0.79 V vs.RHE,higher than the HaberBosch process (<3.4 g h^(-1)g^(-1)cat.).This work may open a new avenue for effective NO_(3)-RR by modulating oxidation states. 展开更多

We introduce our state-of-the art of“vacuum consistent electrochemistry”to an investigation of the interfaces between oxides and ionic liquid(IL).Pulsed laser deposition(PLD)has been one of the powerful and sophisticated techniques to realize nanoscale preparation of high-quality epitaxial oxide thin films.On the other hand,electrochemistry is a simple,very sensitive,and non-destructive analysis technique for solid-liquid interfaces.To ensure the reproducibility in experiment of the interfaces of such epitaxial oxide films,as well as bulk oxide single-crystals,with IL,we employ a home-built PLD-electrochemical(EC)system with IL as an electrolyte.The system allows one to perform all-in-vacuum experiments during the preparation of well-defined oxide electrode surfaces to their electrochemical analyses.The topics include electrochemical evaluations of the oxide’s own properties,such as carrier density and relative permittivity,and the interfacial properties of oxides in contact with IL,such as flat band potential and electric double layer(EDL)capacitance,ending with future perspectives in all-solid-state electrochemistry. 展开更多

A major challenge hindering the large-scale commercialization of lithium-sulfur(Li-S)batteries lies in the sluggish redox kinetics of polysulfides.This study proposes a microstructure design strategy that involves loading densely dispersed CoP nanoparticles onto the surface of MXene layered materials.MXene not only provides a large specificsurface area to support a high density of active CoP nanoparticles,but also offers excellent conductivity and abundant surface functional groups that serve as additional reactive sites.Furthermore,the densely dispersed CoP nanoparticles not only function as the major active sites,but also effectively prevent the self-stacking of MXene sheets,thereby enhancing the microstructural stability.Compared to the coin cells assembled with individual CoP or MXene materials,the battery made by CoP-MXene composite cathode exhibits significantlyenhanced performance,maintaining a high discharge specificcapacity of 632 mA·h·g^(-1) after 200 cycles at a high current density of 2 C.This study provides a novel approach for designing cathode materials for Li-S batteries. 展开更多

Metal-organic frameworks(MOFs),with their ultrahigh specific surface area,uniformly distributed pores,and tunable structures,are promising candidates for next-generation active electrode materials in lithium-ion batteries(LIBs).However,their application is hindered by poor cycling stability due to structural collapse during charge-discharge cycles.To address this issue,we developed an alloy and multi-solvent thermal method strategy to synthesize Co/Zn bimetallic MOFs based on Naphthalenetetracarboxylic acid(NTCA).The resulting petal-like Co/Zn-NTCA MOF demonstrates outstanding electrochemical performance.The incorporation of zinc ions not only significantly enhances cycling stability but also markedly increases the specific capacity of the anode material.At a current density of 200 mA·g^(-1),the Co/Zn(2:1)-NTCA MOF demonstrated an impressive reversible capacity of 956 mA·h·g^(-1) after 150 cycles.Even after 500 cycles,the specific capacity of the electrode remained high,with a value of 438 mA·h·g^(-1) at a current density of 1000 A·g^(-1). 展开更多

The impact of Bacillus subtilis(B.subtilis)on the corrosion behavior(microbiologically influenced corrosion)of two aluminum alloys—7075 aluminum alloy(AA7075)and 2024 aluminum alloy(AA2024)—is investigated in a high-salinity environment.The corrosion mechanism is explored by observing the bacterial growth process and the corresponding measurements.The assessment involves the analysis of surface morphology,corrosion mass loss,and electrochemical tests.Surface morphology reveals the development of B.subtilis and biofilm formation on the surface of the aluminum alloys.Both mass loss and electrochemical tests illustrate the corrosion inhibition effect of B.subtilis on aluminum alloys in a high-salt environment.AA7075 alloy was more affected by the biofilm and had a more pronounced corrosion inhibition effect.After 10 d of testing,in B.subtilis group,AA7075 and AA2024 bode values were elevated by 0.32×10^(4) and 0.24×10^(4)Ω,respectively.The open circuit potential of AA2024 decreased by−0.107 A/cm^(2) under the influence of bacteria,and the dynamic potentiodynamic polarization curve shifted significantly to the left. 展开更多

The intricate sulfur redox chemistry involves multiple electron transfers and complicated phase changes.Catalysts have been previously explored to overcome the kinetic barrier in lithium-sulfur batteries(LSBs).This work contributes to closing the knowledge gap and examines electrocatalysis for enhancing LSB kinetics.With a strong chemical affinity for polysulfides,the electrocatalyst enables efficient adsorption and accelerated electron transfer reactions.Resulting cells with catalyzed cathodes exhibit improved rate capability and excellent stability over 500 cycles with 91.9%capacity retention at C/3.In addition,cells were shown to perform at high rates up to 2C and at high sulfur loadings up to 6 mg cm^(-2).Various electrochemical,spectroscopic,and microscopic analyses provide insights into the mechanism for retaining high activity,coulombic efficiency,and capacity.This work delves into crucial processes identifying pivotal reaction steps during the cycling process at commercially relevant areal capacities and rates. 展开更多

The plasma-coupled electrocatalytic cascade technology with NO_x~-as intermediate product is a potential method to realize green ammonia synthesis.The matching of the formation rate and consumption rate of NO_(2)^(-)as the main absorption product is an important prerequisite for the system to achieve stable operation.Therefore,this paper firstly emphasizes the importance of operating parameters on the cascade system based on the single factor experiment.Secondly,the empirical equation between electrocatalytic operating conditions and NO_(2)^(-)consumption rate was established by response surface analysis.Based on this equation,the electrocatalytic operating parameters were optimized to achieve the dynamic equilibrium between NO_(2)^(-)formation rate and consumption rate.Finally,the techno-economic assessment model was established to calculate the levelized cost of ammonia based on the cascade system,and the single-variable sensitivity analysis was performed to provide the clear guidance for cost reduction. 展开更多

By enhancing surface interaction between metal oxide particles and carbon-based materials,it can effectively improve Faraday capacitance and conductivity,ultimately achieving high energy density with sufficient redox reactions in supercapacitors.Through a gentle biomineralization process and subsequent thermal reduction strategy,we successfully prepared the graphene oxide(GO)wrapping mixed-valence manganese oxides(MnO_(x))and S,P self-codoped carbon matrix porous composite(MnO_(x)@SPC@reduced graphene oxide(RGO)).During the biomineralization process of engineered Pseudomonas sp.(Ml)cells,GO nanosheets functioned as the'soil'to adsorb Mn^(2+)ion and uniformly disperse biogenic Mn oxides(BMO).After undergoing annealing,the MnO_(x) nanoparticles were evenly wrapped with graphene,resulting in the creation of the MnO_(x)@SPC@RGO3 composite.This composite possesses strong C—O—Mn bond interfaces,numerous electroactive sites,and a uniform pore structure.By optimizing the synergistic interaction between the highly conductive graphene and the remarkable surface capacitance of MnO_(x),the MnO_(x)@SPC@RGO3 electrode,with its intercalation Faraday reactions mechanism of■transformations,exhibits an outstanding specific capacity(448.3 F·g^(-1)at 0.5 A·g^(-1)),multiplying performance(340.5 F·g^(-1)at10 A·g^(-1)),and cycling stability(93.8%retention after 5000 cycles).Moreover,the asymmetric all-solidstate supercapacitors of MnO_(x)@SPC@RGO3//PC exhibit an exceptional energy density of 64.8 W·h·kg^(-1)and power density of 350 W·kg^(-1),as well as a long lifespan with capacitance retention of 92.5%after10000 cycles.In conclusion,the synthetic route utilizing biomineralization and thermal reduction exhibits significant potential for exploiting high-performance electrode materials in all-solid-state supercapacitor applications. 展开更多

To solve the serious volume expansion problem of Sb-based anode materials in the alloying/dealloying process,a strategy combining electrospinning and hydrogen reduction is proposed to prepare a series of Sb-based alloys/carbon nanofiber composites(SbM/CNFs,M=Co,Zn,Ni).Inactive elements are innovatively introduced to form Sb based alloys with enhanced stability.The results show that the content of SbCo nanoparticles is high to 69.12%(mass),which are uniformly dispersed in carbon fibers.When evaluated as anode material for SIBs,SbCo/CNFs anode exhibits excellent sodium storage capacity,the initial discharge capacity is 580.0 mA h·g^(-1)at 0.1 A g^(-1),which can hold 483.5 mA h·g^(-1)after 100 cycles.Even the current density increases to 1.0 A g^(-1),the specific capacity still maintains at 344.5 mA h·g^(-1)after 150 cycles.The improved sodium storage capacity is attributed to the synergistic effect of conductive carbon fibers and SbCo nanoparticles with uniform dispersion,which not only provide excellent electronic conductivity,but also enhance structural stability to reduce volume change. 展开更多
