中文摘要：

采用电化学扫描电沉积法在玻碳电极（GC）或氧化铟锡电极（ITO）上经过交替沉积制备了{[PM012O40]^3-/PAMAM}n多层复合膜,通过循环伏安（CV）测试表明多层膜在电极基底表面均匀增长.并以{[PMo12O40]^3-/PAMAM}n多层复合膜为载体在其表面上通过原位电沉积负载上Pt纳米粒子,X射线光电子能谱（XPS）、扫描电镜（SEM）分析结果表明铂纳米粒子成功负载在{[PMo12O40]^3-/PAMAM}n复合膜上.用该方法制备的载铂多层复合膜修饰电极,不仅电极稳定性好,对直接甲醇氧化具有良好的催化活性.

英文摘要：

The novel { [PMo12O40] 3-/PAMAM }n multilayer films were prepared on the GC or ITO electrode surface by the electrochemical scan electrodepositing method,and their homogeneous and uniform traits were verified by cyclic voltammetry.{ [PMo12O40]3-/PAMAM}n multilayer films were used as a supporter for electro-deposition of Pt nanoparticles in situ.XPS,SEM analysis revealed that Pt nanoparticles had been loaded on the surface of the { [PMo12O40] 3-/PAMAM} n multilayer films in the synthesis process.The as-prepared Pt/{ [PMo12O40] 3-/PAMAM } n composite films were stable and exhibited good catalytic activities for direct methanol oxidation.
