摘　　要：采用层层自组装的方法,把多金属氧酸盐PMo12O403-和与Cu2+络合的聚酰胺-胺树形分子PAMAM(PAMAM-Cu2+)交替吸附成膜。X射线光电子能谱(XPS)、紫外可见光谱(UV-Vis)、原子力显微镜(AFM)和循环伏安法(CV)测试表明,PMo12O403-和PAMAM-Cu2+能通过静电作用形成多层膜且膜的增长均一稳定,该多层膜修饰电极对H2O2和NO2-有较好的电催化还原活性。The muhilayers consisting of PMo12O40^3- and metallodendrimer PAMAM-Cu^2＋ were successfully fabricated based on electrostatic imeraction by layer-by-layer assembly. XPS, AFM, UV-Vis absorption spectroscopy and CV proved that the multilayers are uniform and stable. The muhilayers exhibit remarkable electrocatalytic effects on the reduction of H2O2 and NO2^- .
