Ti/PbO2 electrodes doped with Fe or Co were prepared by an electro-codeposition method.The effects of the Fe or Co on Ti/PbO2 electrodes were investigated by the X-ray diffraction(XRD),scanning electron microscope(SEM) and cyclic voltammetry(CV).Compared with the pure Ti/PbO2 electrode,the morphology of Ti/PbO2 electrode doped with either Fe or Co remained nearly unchanged while their structures and performances were varied.The activities of oxygen evolution reaction(OER) were improved in Co doped electrode.The dissolution,re-deposition or crystalline transforming of PbO2 took place during the electroreaction process.In addition,the lifetime of the electrodes might be influenced by such dissolution and re-deposition.
