Electrochemical Behavior of TiO2Nanoparticle Doped WO3Thin Films

摘要

Nanoparticle TiO2doped WO3thin films by pulsed spray pyrolysis technique have been studied on fluorine tin doped (FTO) and glass substrate. XRD shows amorphous nature for undoped and anatase phase of TiO2having (101) plane for nanoparticle TiO2doped WO3thin film. SEM shows microfibrous reticulated porous network for WO3with 600 nm fiber diameter and nanocrystalline having size 40 nm for TiO2nanoparticle doped WO3thin film. TiO2nanoparticle doped WO3thin film shows ~95% reversibility due to may be attributed to nanocrystalline nature of the film, which helpful for charge insertion and deinsertion process. The diffusion coefficient for TiO2nanoparticle doped WO3film is less than undoped WO3.
