摘　　要：本文采用软模板的方法,选取吡咯作为氮源和碳源,通过简单的吡咯的聚合、自组装与热解,制备了聚吡咯碳纳米棒。Pt纳米颗粒通过多元醇法负载在聚吡咯碳纳米棒上。在酸性条件下对Pt/PCNRs催化剂进行甲醇电氧化测试,发现Pt/PCNRs的催化活性和稳定性都比商业化的Pt/XC-72有明显的提升。In this paper, polypyrrole carbon nanorods were prepared by simple pyrrole polymerization, self-assembly and pyrolysis by using soft template method and pyrrole as nitrogen source and carbon source. The Pt nanoparticles are supported on the polypyrrole carbon nanorods by a polyol method. The Pt/PCNRs catalyst was subjected to methanol electrooxidation test under acidic conditions. It was found that the catalytic activity and stability of Pt/PCNRs were significantly improved compared with commercial Pt/C.
