Photo electrochemical Performance and Photo catalytic Activity of Porous WO

Porous WO3 films were successfully synthesized by a simple and easy method using polystyrene spheres (PS) as templates. The PS array covered F: SnO2 coated glass (FTO) as the substrate was first prepared via electrodeposition method. Ordered porous WO3 films were obtained by electrophoretic deposition in peroxy-tungstic acid sol. The characterization and photo electrochemical properties of samples were investigated. The results show that the porous WO3 film displays the enhanced performance compared with the compact films without PS templates
