| 摘 要： | 采用软模版法合成聚苯胺前躯体，通过改变过渡金属制备出PANI-FeCo-C、PANI-Fe-C、PANI-Co-C和PANI-C质子交换膜燃料电池(PEMFC)阴极非贵金属催化剂。电化学测试结果表明：4种催化剂中，PANI-Fe-C的催化活性最好，其氧还原反应起始电位达到0.87V。通过X射线衍射光谱（XRD）、拉曼（Raman）光谱、透射电子显微镜（TEM）、能量色散X射线光谱（EDS）和X射线光电子能谱（XPS）测试可知，PANI-Fe-C催化剂中含有较多晶格畸变的碳和石墨型的氮，这些特性是其具有优越氧还原催化性能的重要原因。

| Abstract: | Polyaniline (PANI) has been used as a precursor to prepare PANI-FeCo-C, PANI-Fe-C, PANI-Co-C and PANI-C non precious metal catalysts by a soft template method for use in proton exchange membrane fuel cells (PEMFC). Electrochemical measurements show that the PANI-Fe-C catalyst has a higher electrocatalytic activity than the other three catalysts. The ORR onset potential of the PANI-Fe-C catalyst is measured to be 0.87V. X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) show that the PANI-Fe-C catalyst contains more carbon lattice distortion and graphitic nitrogen than the others, which provides a good explanation for its excellent ORR performance. |
