本文采用聚合法制备聚吡咯，并用三种方法合成了钴聚吡咯配合物。通过XRD、红外、XPS和循环伏安等表征手段，讨论了三种方法对聚吡咯催化剂结构及氧还原性能的影响。结果表明，在这三种制备方法中，钴与PPy-CNTs的结合方式不同，从而引起其氧还原性能的不同。 在NaBH4+NaOH还原气氛下制备了不同钴含量的聚吡咯催化剂，并对其进行了红外光谱、电子探针和循环伏安等表征。研究结果表明金属含量不同将影响催化氧还原的性能。氮含量为1%，Co/N比例为1:2的样品氧还原电位最高。Co-PPy composites adsorbed on the carbon nanotubes were prepared by three methods. These samples were characterized by using XRD, FTIR, X-ray photoelectron spectroscopy (XPS), and cyclic voltammetry (CV)，etc. The structural characterizations and the electrochemical properties of the three samples are different. The results showed that the interaction of Co and PPy is different due to the reduction...学位：博士后院系专业：化学化工学院化学系_化学学号：BH1700019
