摘要: Homogeneous and transparent lanthanum La-doped TiO2 nanocrystalline thin films were deposited on pure titanium substrates by sol gel dip coating method. The surface structures, morphologies electrocatalytic activities of the prepared nano-TiO2 film electrodes studied X-ray diffraction (XRD), scanning electron microscopy (SEM) Cyclic voltammetry (CV). results demonstrated that optimum molar proportion La was 0.5%. This La-nanoTiO2 electrode (Ti/0.5%La nano-TiO2) showed a higher activity than undoped (Ti/nano-TiO2)
