| 摘 要： | 采用循环伏安法在玻碳电极上制备了{H3PMo12O40]/Pt/PAMAM}复合膜,用X射线光电子能谱(XPS)、扫描电子显微镜(SEM)、电子能谱技术(EDS)、原子力显微镜(AFM)和循环伏安法(CV)研究了膜的组成、形貌及其对甲醇的电催化氧化活性。结果表明,Pt纳米粒子在PAMAM基底上分散均匀;最外层沉积H3PMo12O40]后,与相同条件下制备的Pt/PAMAM膜相比,{H3PMo12O40]/Pt/PAMAM}复合膜修饰电极对甲醇的氧化有更强的电催化活性。

| Abstract: | The {H3PMo12O40]/Pt/PAMAM}composite film was prepared on glassy carbon electrode(GCE) by cyclic voltammetry scanning.The film and the electrocatalystic activity toward methanol were characterized by X-ray photoelectron spectroscopy(XPS),scanning electron microscope(SEM),energy disperse spectroscopy(EDS),atomic force microscopy(AFM) and cyclic voltammetry(CV).The result shows that the Pt nanoparticles are well dispersed on the PAMAM film,and the adding of H3PMo12O40] on the surface of Pt nanoparticles can ... |
