Preparation of PbO2+nano-WO3 Composite Electrode on Ti Substrate by Composite Electrodeposition and Its Oxygen Evolution Activity†

doi:10.7503/cjcu20140664

Abstract

Abstract:

PbO₂+nano-WO₃ composite electrode materials were prepared by the composite electrodeposition method on Ti substrate with the intermediate SnO₂-Sb₂O₅ layer. The composition, structure and morphology of the composite electrode materials were investigated by X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS), scanning electron microscopy(SEM) analyses and double layer capacitance methode. The results indicate that porosity, roughness and electrochemically effective area of the composite electrode surface are increased because of the embedded nano-WO₃. Then, the composite electrodes were used as anodes for oxygen evolution reaction(OER). The activities for the OER of the composites were explained by recording linear scanning voltammograms and Tafel plots. In contrast with the PbO₂ electrode without nano-WO₃, oxygen evolution onset potentials of the composite electrodes become lower, the overpotentials for oxygen evolution of composite electrodes are decreased, and the OER activities are improved significantly. The overpotential for oxygen evolution at the composite electrode could be lowered by approximately 300 mV compared to that of PbO₂ electrode without nano-WO₃.
