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
