Ni2P
metal· Ni2P
Ni₂P is an intermetallic nickel phosphide compound that belongs to the metal phosphide family, characterized by strong metallic bonding with embedded phosphide phases. It is primarily investigated as a catalyst material and emerging functional compound in electrochemistry and materials science, where its combination of metallic conductivity and chemical reactivity makes it attractive for hydrogen evolution reactions, oxygen reduction, and other electrochemical applications. Ni₂P offers advantages over pure nickel in catalytic efficiency and corrosion resistance in specific electrochemical environments, positioning it as a research-driven alternative to precious-metal catalysts in energy conversion devices.
