摘　　要：在涂有中间层SnO2-Sb2O5的Ti基体上,采用阳极复合电沉积法制备了Ti/SnO2-Sb2O5/PbO2+nano-Co3O4复合电极材料,利用X射线衍射(XRD)、X射线光电子能谱(XPS)和扫描电子显微镜(SEM)等方法研究了制备条件对该复合电极材料组成、结构和形貌的影响.结果表明,纳米Co3O4的掺杂可提高PbO2电极表面的粗糙度和空隙率;沉积电位、镀液中Co3O4粒子浓度及有机溶剂的添加等均对镀层中Co3O4的嵌入量有较大影响.Ti/SnO2-Sb2O5/PbO2＋nano-Co3O4 composite electrode material was prepared by the anode composite electrodeposition method on Ti substrate with the intermediate SnO2-Sb2O5 layer.The influences of preparation conditions on the composition,structure and morphology of the composite material were investigated by X-ray diffraction（XRD）,X-ray photoelectron spectroscopy（XPS） and scanning electron microscope（SEM） analyses.The results show that porosity and roughness of the PbO2 surface are increased because of the embedded Co3O4;the Co3O4 embedding content is effected by the deposition potential,nano particles concentration and the addition of organic reagent.
