Abstract: Abstract 3D METALS PHOSPHO-SULFIDE CATALYST FOR SOR OR OER AND HER IN A SINGLE SYSTEM ELECTRODEPOSITION PROCESS An electrocatalyst comprises a nickel substrate bearing a catalytic layer of at least one 3d transition metal with phosphorus and sulfur, active for the sulfide-oxidation, hydrogen-evolution and oxygen-evolution reactions. A single electrodeposition in a cell with nickel-based electrodes produces both anode and cathode, the substrate losing mass via a dissolution-reconstruction mechanism. For sulfide oxidation the catalyst needs no drying and is used directly after a mild sodium-sulfide prewash, enabling in-situ deposition on the electrolyser itself, demonstrated at about 100 cm², about 100 mA cm?² and about 0.9 V; the working surface reconstructs to a sulfur- tolerant (oxy)hydroxide/oxysulfide phase. For hydrogen and oxygen evolution the anode and cathode from the same process are dried to lock the amorphous structure. Dilute hydrochloric acid may be added to reduce nickel loss while retaining performance. The self-supported, membrane-free electrodes are used to split H2S into hydrogen and sulfur and for overall water electrolysis. Fig 1, 2 & 3.
