Ni₃S is an intermetallic nickel sulfide compound that belongs to the nickel-sulfur family of materials. It is primarily investigated in electrochemistry and catalysis research rather than as a commodity structural material, with particular interest in hydrogen evolution reaction (HER) catalysts, energy storage systems, and corrosion-resistant coatings. Engineers and researchers select nickel sulfides for applications requiring excellent catalytic activity and electrical conductivity in harsh or corrosive aqueous environments, offering advantages over pure metals in stability and performance in pH-variable conditions.
