Electrocatalytic Water Splitting through the Ni _x S _y Self-Grown Superstructures Obtained via a Wet Chemical Sulfurization Process.

ABSTRACT: We report water-splitting application of chemically stable self-grown nickel sulfide (Ni _x S _y ) electrocatalysts of different nanostructures including rods, flakes, buds, petals, etc., synthesized by a hydrothermal method on a three-dimensional Ni foam (NiF) in the presence of different sulfur-ion precursors, e.g., thioacetamide, sodium thiosulfate, thiourea, and sodium sulfide. The S^2- ions are produced after decomposition from respective sulfur precursors, which, in general, react with oxidized Ni²⁺ ions from the NiF at optimized temperatures and pressures, forming the Ni _x S _y superstructures. These Ni _x S _y electrocatalysts are initially screened for their
