Fe7S8
metal· JVASP-96925· Fe7S8
Fe7S8 is an iron sulfide compound belonging to the family of transition metal sulfides, representing a mixed-valence iron sulfide phase with potential applications in energy storage and catalysis research. This material is primarily of academic and emerging industrial interest rather than an established commodity material, studied for its electrochemical properties in battery systems and as a catalyst precursor for hydrogen evolution and other reactions. Its notable characteristic among iron sulfides is the specific iron-to-sulfur ratio, which influences its electrical conductivity and redox activity compared to common phases like FeS and FeS2.
