摘要 以XC-72炭黑为载体,原位聚合制备碳载聚吡咯(PPy)复合载体,采用浸渍法及1 073 K高温热处理,制备Co-PPy/C催化剂。通过XRD、透射电镜(TEM)、元素分析(EA)和X射线光电子能谱(XPS)测试,对Co-PPy/C催化剂的结构和形貌进行分析。循环伏安和线性扫描伏安(LSV)测试结果表明:Co0.50-PPy/C催化剂在酸性介质中具有良好的氧还原活性。在0.5 mol/L H2SO4中,353 K下处理72 h后,催化剂中的钴粒子全部被溶出;催化剂中吡啶氮和石墨氮是此类催化剂的氧还原反应(ORR)活性中心。 Carbon supported polypyrrole（PPy） composite support was prepared by in-situ polymerization using XC-72 carbon black as support, Co-FPy/C catalyst was prepared by impregnation method and high temperature treated at 1 073 K. The structure and morphology of Co-PPy/C catalysts were analyzed by XRD, transmission electron microscopy（ TEM ） , element analysis（ EA ）and X-ray photoelectron spectroscopy（XPS）. Results of cyclic vohammetry and linear sweep voltarrmletry（LSV）tests showed that Coo 50-PPy/C catalyst had fine ORR activity in acid medium. All cobalt ions were dissolved out after soaking in 0. 5 mol/L H2SO4 solution at 353 K for 72 h. Pyridinic-like nitrogen and graphitic-like nitrogen in catalyst were the oxygen reduction reaction（ORR） active site.
