Photoelectrochemical and photocatalytic activities of bilayered TiO2/Ga:WO3 photoelectrode by spray pyrolysis technique

Abstract
Abstract WO 3 , Ga:WO 3 and bilayered TiO 2 /Ga:WO 3 photocatalysts are synthesized by spray pyrolysis technique. Synthesized films are characterized by various characterization techniques such as structural, morphological and photoelectrochemical properties. Synthesized films are polycrystalline in nature. The TiO 2 /Ga:WO 3 photoelectrode exhibits highest photocurrent density (1569 μA/cm 2 ) than that of pure WO 3 and Ga:WO 3 films due the prevent the recombination of photogenerated electron-hole pairs. Photoelectrocatalytic activities of WO 3 , Ga:WO 3 and bilayered TiO 2 /Ga:WO 3 photoelectrodes are tested for photodegradation of salicylic acid as a model organic pollutant. The results show that the bilayered TiO 2 /Ga:WO 3 photocatalyst has an efficient photocatalytic ability as compared to pure WO 3 and Ga:WO 3 photocatalysts.
