· Co9 Se8

Co₉Se₈ is a cobalt selenide compound semiconductor belonging to the transition metal chalcogenide family. It is primarily investigated in research and emerging applications for its semiconducting properties and potential catalytic behavior, rather than as an established commercial material. This compound is of interest in electrochemistry and materials research communities for energy storage, electrocatalysis, and thermoelectric applications where layered or mixed-valence metal chalcogenides show promise.
