· JVASP-31720· NbW5Se12

NbW5Se12 is a mixed-metal selenide compound combining niobium and tungsten with selenium, belonging to the family of transition metal chalcogenides. This is a research-phase material primarily investigated for its electronic and catalytic properties rather than as a structural metal, despite its metallic classification. Interest in this compound centers on potential applications in energy conversion and catalysis, where layered selenide materials have shown promise as alternatives to conventional catalysts and semiconductors.
