| 摘 要： | 通过简便的方法合成出了Pt-CeOx/CNxNT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CNxNT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-CeOx/CNxNT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。

| Abstract: | 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. |
