Abstract

Development of nanostructured photocatalysts for harnessing solar energy in energy-efficient and environmentally benign way remains an important area of research. Pure and WO₃-surface modified thin films of TiO₂ were prepared by magnetron sputtering on indium tin oxide glass, and photoelectrochemical and photocatalytic activities of these films were studied. TiO₂ particles were <50 nm, while deposited WO₃ particles were <20 nm in size. An enhancement in the photocurrent was observed when the TiO₂ surface was modified WO₃ nanoparticles. Effect of potential, WO₃ amount, and radiations of different wavelengths on the photoelectrochemical activity of TiO₂ electrodes was investigated. Photocatalytic activity of TiO₂ and WO₃-modified TiO₂ for the decolorization of methyl orange was tested.
