CoP₂ is a cobalt phosphide compound semiconductor with a metallic-like crystal structure, belonging to the family of transition metal phosphides. This material is primarily investigated for electrochemical and catalytic applications, particularly as an active catalyst material for hydrogen evolution, oxygen reduction, and water splitting reactions, where it competes with precious metal catalysts like platinum. CoP₂'s combination of relatively high stiffness and metallic conductivity makes it attractive for researchers seeking earth-abundant alternatives to platinum-group catalysts in energy conversion and environmental remediation technologies.
