Optical properties including band gap of many wide band gap semiconductor oxides like TiO2, ZnOand SnO2 has limitations over their bare use in photocatalytic applications. Thus, in view of above,tungsten oxide (WO3), an intermediate band gap metal oxide has been selected to explore forphotocatalytic degradation application. Present work deals with the preparation of WO3 using a simplechemical solution based spin coating method. The prepared sample has been characterized for structural,morphological and photocatalytic properties. Degradation experiment of dye was carried outsystematically at the optimized conditions of pH 4 and contact time (120 min) between dye andcatalyst. For optimized conditions, WO3 showed about 75% of degradation of rhodamine-B. Thissuggests that a huge scope to optimize preparative parameters for WO3 to explore it as an alternative toconventional metal oxides.
