CoP (cobalt phosphide) is an intermetallic compound combining cobalt with phosphorus, belonging to the transition metal phosphide family. It is primarily investigated as an electrocatalyst for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in electrochemical applications, offering a lower-cost alternative to platinum-group catalysts while maintaining competitive catalytic activity. CoP is also explored in energy storage systems, water splitting devices, and emerging battery technologies where its electronic properties and surface reactivity provide advantages over conventional metal hydroxides or oxides.
