· JVASP-121973· HoNi4P2

HoNi4P2 is an intermetallic compound combining holmium, nickel, and phosphorus, representing a rare-earth transition metal phosphide. This material is primarily of research interest rather than established industrial use, explored for its potential in magnetic applications, catalysis, and energy storage devices where rare-earth elements provide enhanced functional properties. The nickel-phosphide base family has demonstrated promise in hydrogen evolution reactions and electrochemical systems, making HoNi4P2 a candidate compound in emerging energy conversion and materials chemistry research.
