Ni3 Se2

Ni3Se2 is a nickel selenide compound semiconductor that belongs to the transition metal chalcogenide family, offering distinctive electronic and catalytic properties. This material is primarily investigated for electrochemical energy storage and conversion applications, particularly as a cathode material in batteries and as an electrocatalyst for water splitting and oxygen reduction reactions, where its layered crystal structure and tunable electronic properties provide advantages over conventional oxide-based alternatives. While still largely in the research and development phase, Ni3Se2 is gaining attention in next-generation energy device engineering due to its superior ion transport characteristics and potential for low-cost synthesis compared to precious-metal catalysts.
