· Fe2 W4 O16

Fe₂W₄O₁₆ is a mixed-valence iron tungstate semiconductor compound belonging to the tungsten oxide family of transition metal oxides. This material is primarily of research interest for photocatalytic and electrochemical applications, where its layered structure and electronic properties make it relevant to water treatment, environmental remediation, and energy conversion technologies. While not yet widely commercialized, iron tungstates represent a promising class of earth-abundant alternatives to rare-earth-based semiconductors for catalytic systems.
