| 摘 要： | 采用微波多元醇法合成了Pt/C、Pt-M(Fe、Co、Ni)/C电催化剂,通过X-射线衍射仪(XRD)和透射电镜(TEM)测试手段对催化剂的微观结构、表面形貌等物理性能进行表征,并对其电化学性能进行了比较。测试结果表明:催化剂均高度分散在Vulcan XC-72碳载体上,Pt/C、Pt-Fe/C、Pt-Ni/C和Pt-Co/C电催化剂的平均粒径分别为:3.4、2.6、2.8、3.1 nm。在室温28℃下测得的电化学性能结果表明:合成催化剂在甲醇中的氧化活性高低顺序为:Pt-Fe/CPt-Co/CPt-Ni/CPt/C,催化剂电催化性的稳定性高低顺序为:Pt-Ni/CPt-Co/CPt-Fe/CPt/C,合成的Pt-M/C电催化剂催化性能均比Pt/C催化剂高,掺入合金Fe、Co和Ni后的Pt-M/C催化剂均具有较好的抗CO中毒的能力。 |
