摘要

The electrodeposition of Co-doped PbO_2 on stainless steel as support was investigated with the aim of producing electrodes with improved catalytic activity.The electrodeposition conditions(current densities,hydrodynamic conditions,time,bath composition)influenced the deposit of Co-doped PbO_2 electrode.The surface analysis data obtained by SEM,EDX and XRD showed differences in the physicochemical properties of Co-doped PbO in comparison with undoped PbO_2.Voltammetric data recorded by CV provided information regarding the electrochemical behaviour,including the electrode stability and catalytic activity for anodic oxygen evolution reaction in acidic medium(0.1
