· Ni3S2

Ni3S2 is a nickel sulfide intermetallic compound that belongs to the family of metal sulfides, typically produced through controlled synthesis or as a byproduct in nickel processing and sulfide ore beneficiation. While not a mainstream structural material, Ni3S2 has attracted interest in electrochemistry and energy storage applications—particularly as a catalyst for hydrogen evolution and oxygen reduction reactions—and in research contexts exploring sulfide-based materials for battery and fuel cell technologies. Its selection would be driven by specialized electrochemical performance requirements rather than conventional mechanical load-bearing roles, and it represents an emerging material class for next-generation clean energy devices.
