Interface Engineering of Iron-Tin-Cobalt Sulfide/Oxide Heterostructure Catalysts for Synergistic Water Splitting

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

Lattice Distorted Pt Wrinkle Nanoparticles for Efficient Hydrogen Electrocatalysis

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

Efficient Low-Coordination Copper-Based Catalysts for Selective CO2 Reduction to Ethylene

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
