W3 O9
semiconductor· W3 O9
W₃O₉ is a tungsten oxide semiconductor compound belonging to the family of mixed-valence tungsten oxides, which exhibit interesting electrochromic, photocatalytic, and electronic properties. This material is primarily investigated in research and emerging applications rather than as an established commercial product, with potential in photoelectrochemical water splitting, gas sensing, and smart windows due to its bandgap characteristics and surface reactivity.
