Ni2 Se2

Ni₂Se₂ is a nickel selenide semiconductor compound belonging to the transition metal chalcogenide family, notable for its layered crystal structure and tunable electronic properties. This material is primarily investigated in research contexts for energy storage and catalytic applications, where its semiconducting behavior and chemical reactivity make it attractive as an alternative to more conventional materials in battery electrodes and electrochemical catalysts. Engineers consider this compound for applications requiring earth-abundant transition metal alternatives to precious metal catalysts, though it remains largely in development rather than widespread commercial deployment.
