| 摘 要： | 通过低温氧化法制备了聚吡咯碳(PPyC)载体,并以PPyC为载体制备了纳米Pd催化剂(Pd/PPyC)。采用X射线衍射、扫描电镜、透射电镜等手段对载体PPyC及催化剂Pd/PPyC进行了表征,通过分析电化学比表面随循环伏安次数的变化及多电势阶跃实验结果表明,以PPyC为载体的Pd/PPyC催化剂具有比碳黑作载体制备的Pd/C催化剂更高的稳定性。

| Abstract: | Polypyrrole composite （PPyC） encompassed of carbon black were synthesized by low temperature oxidation of pyrrole on black carbon and the nanosized Pd catalyst supported by PPyC was prepared.The support PPyC and the catalyst Pd/PPyC were characterized by X-ray diffraction, scanning electron microscopy and trans- mission electron microscopy.The results from formic acid oxidation showed that the Pd/PPyC catalyst exhibits better stability than Pd/C. |
