| 摘 要： | 采用水热法制备了MnO2纳米棒,然后电沉积Pt合成了Pt-MnO2/C复合物.利用X射线衍射仪(XRD)和扫描电子显微镜(SEM)对MnO2的晶型和形貌进行了表征,并运用循环伏安(CV)法考察了Pt-MnO2/C在不同条件下对乙醇的电催化活性.实验结果表明,该催化剂在乙醇浓度为0.5 mol/L,H2SO4浓度为0.5 mol/L,电沉积Pt 40段时对乙醇的电催化活性最好. |

| Abstract: | MnO2 nanorod was prepared by a hydrothermal method,and then Pt was electrodesposited to synthesise Pt-MnO2/C composite catalyst.The crystal and morphology of MnO2 were characterized by X-ray diffraction(XRD) and scanning electron microscopy(SEM),respectively.The electrochemical activity of Pt-MnO2/C for ethanol oxidation was investigated under different conditions by cyclic voltammetry(CV) method.The results show that the best catalytic activity of composite catalyst for ethanol electrooxidation is obtained... |
