· Na2H4Pt

Na2H4Pt is a complex hydride compound containing platinum and sodium, belonging to the family of metal hydrides and intermetallic compounds. This is primarily a research and development material rather than a conventional structural alloy, investigated for its potential in hydrogen storage, catalysis, and energy conversion applications where platinum's catalytic properties combine with hydrogen-rich chemistry. The material's significance lies in fundamental studies of metal-hydrogen interactions and advanced energy technologies, though industrial-scale deployment remains limited.
