· W6 O18

W6O18 is a tungsten oxide semiconductor compound belonging to the family of polyoxometalates and reduced tungsten oxides, which exhibit mixed-valence electronic properties and semiconducting behavior. This material is primarily investigated in research contexts for photocatalytic applications, electrochemical energy storage, and gas sensing, where its layered structure and oxygen vacancy chemistry offer potential advantages over conventional oxides in catalytic activity and electron transport. W6O18 represents an intermediate oxidation state tungsten compound that bridges between fully oxidized WO3 and metallic tungsten, making it of particular interest for applications requiring tunable band gaps and enhanced charge carrier mobility.
