· JVASP-109516· Co2S3

Cobalt sulfide (Co₂S₃) is a transition metal sulfide compound that belongs to the family of metal chalcogenides. It is primarily investigated as a research material for electrochemical and catalytic applications, rather than a conventional structural engineering material. This compound is of particular interest in energy storage, electrocatalysis for hydrogen evolution, and emerging battery technologies, where its mixed-valence cobalt centers and sulfide chemistry offer advantages over pure oxides or single metal sulfides.
