· JVASP-112599· Co3P

Co₃P is an intermetallic cobalt phosphide compound that belongs to the metal phosphide family, characterized by strong metal-nonmetal bonding that imparts unique catalytic and electrochemical properties. This material is primarily investigated for electrochemical applications, particularly as a catalyst for hydrogen evolution reactions (HER) and oxygen evolution reactions (OER) in water splitting and fuel cell systems, where it offers improved activity and stability compared to noble-metal catalysts. Co₃P is largely a research and emerging material rather than an established industrial commodity, with growing interest in sustainable energy conversion and green hydrogen production driving its development as a cost-effective alternative to platinum-group catalysts.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
