· JVASP-26076· Tm2Ni12P7

Tm2Ni12P7 is an intermetallic compound combining thulium, nickel, and phosphorus, belonging to the rare-earth transition metal phosphide family. This is a research-phase material primarily investigated for its potential in hydrogen storage, catalysis, and energy conversion applications due to the favorable electronic properties that rare-earth phosphides can exhibit. While not yet established in high-volume industrial production, compounds in this material family are of particular interest for clean energy technologies where the combination of rare-earth elements and transition metals creates active sites or favorable thermodynamic pathways.
