摘　　要：以不锈钢(SS)为基体,聚苯乙烯(PS)微球为模板,采用直流电沉积法制备了SS/ZnO/PbO_(2)阵列电极。通过扫描电镜(SEM)分析和线性扫描伏安法(LSV)测试,研究了电流密度、施镀时间和Pb(NO_(3))_(2)质量浓度对电极活性层微观形貌和析氧电催化性能的影响。结果表明,在电流密度5.0 mA/cm^(2)和Pb(NO_(3))_(2)质量浓度190 g/L的条件下施镀25 min所得SS/ZnO/PbO_(2)阵列电极表面呈规则的花瓣状阵列结构,晶粒均匀、致密,电催化活性优异。A stainless steel(SS)based ZnO/PbO_(2) array electrode was prepared by direct-current electrodeposition using polystyrene(PS)microspheres as template.The effects of current density,electrodeposition time,and Pb(NO_(3))_(2) mass concentration on micromorphology of the electroactive layer and electrocatalytic activity of the electrode for oxygen evolution reaction were studied by scanning electron microscopy(SEM)and linear scanning voltammetry(LSV).The results showed that the SS/ZnO/PbO_(2) array electrode obtained by electrodeposition at a current density of 5.0 mA/cm^(2) and a Pb(NO_(3))_(2) mass concentration of 190 g/L for 25 min featured a regular petal-like arrayed structure with uniform and compact grains,and excellent electrocatalytic activity.
