中文摘要：

通过NaH2PO2自分解方法制备了高分散性的Pt-P／C催化剂，并且使用X射线衍射（XRD）、透射电子显微镜（TEM）等表征手段对催化剂进行了表征，NaH2PO2的加入可有效降低催化剂的粒径，约为2．3nm。此外，亦用多种电化学测试手段测试了P的掺杂对甲醇的电催化氧化性能的影响，测试结果表明Pt—P／C催化剂不但能够增强催化剂对甲醇催化氧化的活性，而且还能够提高催化剂的稳定性。该测试结果表明Pt-P／C催化剂是一类具有潜在应用前景的直接甲醇燃料电池阳极催化剂。

英文摘要：

Highly dispersed Pt-P/C catalyst was prepared by the self decomposition of NaH2PO2, and it was characterized by characterized by transmission electron microscopy （TEM）, X-ray diffraction （XRD）. The ad- dition of could reduce the platinum particle size effectively, and the mean size of the Pt-P particles was about 2.3nm. Furthermore, the effect of P doping towards the oxidation of methanol were also demonstrated by sev- eral electrochemical measures. The results showed that carbon-supported Pt-P catalyst exhibits higher activity and stability for the oxidation of methanol. Therefore, the Pt-P/C nanoparticles was a promising anode catalyst in DMFC.
