| 摘 要： | 通过循环伏安法(CV),计时电流法(CA)和线性扫描法(LSV)对二甲氧基甲烷的电氧化特性进行了研究.发现当用Ho3+修饰Pt/C催化剂电极后可以大幅度提高电极对DMM的电催化活性.热处理Ho3+修饰后Pt/C催化剂电极,可进一步提高该电极对DMM的电催化氧化活性. |

| Abstract: | The electro-oxidation characteristics of dimethoxymethane(DMM),which is a possible alternative fuel for direct methanol fuel cell(DMFC),were carried out by cyclicvoltammetry(CV)and chronoamperometry(CA)at Pt/C catalyst and the Pt/C electrodes modified with Ho3+.The eletrocatalytic activities were highly improved after the Pt/C electrodes were modified with Ho3+.A new oxidation peak appeared at more negative potential after the heat-treatment of the electrodes modified with Ho3+,which made the electrode more... |
| Keywords: | direct methanol fuel cell electrocatalyst Dimethoxymethane rare earth element Ho3+ |
