Single-atom sites have been widely used in various fields of electrocatalysis due to their high atomic utilization, mass activity, and selectivity. However, due to the inherent characteristics of single metal centers, single-atom sites have limitations in catalyzing multi-electron reactions. Dual Atom Sites (DASs) have garnered significant attention as promising candidates because neighboring active sites can … Read more
Electrocatalytic conversion of carbon dioxide (CO2) into useful fuels and chemical feedstocks is an emerging approach to alleviate global warming and reduce reliance on fossil fuels. Methanol (CH3OH), as one of the most important and widely used liquid fuels generated through CO2 reduction, is crucial in the chemical industry. In this review, we reveal the … Read more
Electrooxidizing ethanol to value-added acetic acid is a typical case of replacing the oxygen evolution reaction to promote the cathodic hydrogen evolution reaction and save energy.This paper proposes a colloidal strategy for preparing nickel-iron bimetallic alloy nanoparticles (NPs) as efficient electrocatalysts for ethanol electrooxidation in alkaline media. In a 1.0 M potassium hydroxide (KOH) solution … Read more
To achieve large-scale hydrogen production through water electrolysis, it is crucial to develop non-precious metal catalysts for the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). Here, we prepared a tin, iron, and cobalt-based sulfide/oxide heterostructure catalyst (FeSnCo0.2SxOy/NF) on nickel foam using a solvothermal method. FeSnCo0.2SxOy/NF outperforms IrO2||Pt/C electrolyzers at a current density of … Read more
Introducing lattice distortion to modulate the surface of platinum (Pt) has become an extremely effective strategy to significantly enhance the kinetics of hydrogen evolution and oxidation reactions in alkaline environments.In this study, we prepared lattice distorted platinum wrinkle nanoparticles (LD-Pt WNPs) for efficient hydrogen electrocatalysis.LD-Pt WNPs not only surpassed the performance of the Pt/C benchmark … Read more
According to previous literature, the C-C coupling step in the CO2RR reaction is widely considered to be the core for producing C2 products, especially ethylene. Therefore, adjusting the spatial configuration of Cu to modulate the adsorption of *CO, thereby facilitating CO-CO coupling, is regarded as an effective method to promote ethylene production.The strong adsorption of … Read more
