摘　　要：通过简便的方法合成出了Pt-CeO_x/CN_xNT催化剂。该催化剂以聚吡咯纳米管碳化后的含氮碳纳米管作为载体,以氧化铈作为助催化剂。实验表明,由于二氧化铈的储氧性能,也由于CN_xNT载体中氮元素的促进作用和其本身独特的一维中空结构,Pt-CeO_x/CN_xNT催化剂的氧还原性能明显高于商业Pt/C。而催化剂优秀的稳定性则源于二氧化铈对Pt纳米颗粒和载体的保护作用。A novel catalyst was synthesized using CNx nanotube(CNxNT)converted from polypyrrole nanotube as support and CeOx as co-catalyst.The as-prepared Pt-CeOx/CNxNT catalyst showed superior ORR activity compared to Pt/CNxNT and commercial Pt/C catalyst,which is attributed to the existence of CeOx,pyridine-like nitrogenin support and the unique hollow tube nanostructure of CNxNT support.Moreover,the presence of CeOx can significantly enhance the durability for both Pt nanoparticles and support.
