Scalable one-step synthesis of TiO2/WO3 films on titanium plates with an efficient electron storage ability

摘要

We describe a scalable method to synthesize TiO2/WO3 film electrodes through a one-step oxidation of Ti plates in a mixture of H2O2 and peroxotungstic acid solution. This composite film with a relatively low content of hexagonal phase WO3 displayed an excellent electron storage ability.
