· JVASP-96907· FeMo3S4

FeMo3S4 is an iron molybdenum sulfide compound belonging to the ternary metal sulfide family, characterized by mixed-valence transition metal chemistry. This material is primarily investigated in electrochemistry and catalysis research, where it shows promise for hydrogen evolution reactions (HER) and other energy conversion applications as a potentially cost-effective alternative to platinum-group catalysts. Its notable advantage lies in combining earth-abundant elements (iron and molybdenum) with tunable electronic properties, making it of significant interest for sustainable energy technologies, though industrial-scale deployment remains limited compared to established catalytic materials.
