Ni4 Se8
metal· Ni4 Se8
Ni₄Se₈ is a nickel selenide compound belonging to the metal chalcogenide family, typically investigated as a layered or mixed-valence material with potential semiconductor or electrocatalytic properties. This is primarily a research-phase compound studied for energy storage and conversion applications, particularly in electrochemistry and catalysis contexts, rather than a mature commercial engineering material. Its appeal lies in the combination of nickel's redox activity with selenium's electronic properties, offering potential advantages in hydrogen evolution catalysts and battery electrode materials compared to single-element alternatives.
