| 摘 要： | 应用湿化学法制备RuO2/C纳米复合物,并以其为载体借助微波法制备成Pt/RuO2/C催化剂.使用透射电镜和X射线衍射分析RuO2/C载体、Pt/RuO2/C催化剂的形貌及晶体结构;循环伏安、稳态阳极腐蚀和旋转圆盘电极等测试电化学性能.结果表明,Pt/RuO2/C催化剂具有良好的耐甲醇渗透性和稳定性,可有效延长催化剂的使用寿命.本文为探索新型高性能DMFC阴极催化剂之制备提供了一条较好的途径.

| Abstract: | Instability of the carbon-supported Pt(Pt/C) catalyst at the cathode is one of the key technical challenges for the development of Direct Methanol Fuel Cells(DMFCs).In this paper,an efficient approach to enhancing the stability of the cathode catalyst was explored by designing and synthesizing a novel nanocomposite support,RuO2 coated carbon black(RuO2/C).Firstly,a wet chemical method was employed to synthesize the RuO2/C nanocomposite,from which Pt/RuO2/C catalyst was further prepared by a microwave method... |
