NiSe₂ (nickel diselenide) is an intermetallic compound combining nickel and selenium, belonging to the family of transition metal chalcogenides. While primarily studied as a research material, it shows promise in electrochemistry and energy storage applications due to its layered crystal structure and electronic properties that support catalytic activity. This compound is being investigated as a cost-effective alternative to precious-metal catalysts in hydrogen evolution and oxygen reduction reactions, making it relevant for emerging clean energy technologies rather than established industrial applications.
