摘　　要：制备了导电高分子聚苯胺与活性炭的复合载体(PAn C),用PAn C作为载体制备的钯催化剂性能优于单独活性炭作为载体制备的催化剂。此外掺杂十二烷基磺酸钠制备的聚苯胺碳载体(PAn C-S)具有比PAn C更低的电荷传递电阻,10#25 nm的介孔数量明显增加,比表面积增大到94.9 m2/g。PAn C-S与PAn C粒径均匀,粒径均在30 nm左右。以PAn C-S和PAn C为载体制备的钯催化剂比活性炭作载体制备的钯催化剂具有更大的电化学比表面积,分别为84.7和62.6 m2/g。对甲酸的氧化具有更高的电化学活性和稳定性。The compo site support （ PAnC） with conductive polymer polyaniline and activated carbon are prepared.The catalytic performance of the Pd catalyst prepared with PAnC as a support is better than that of the catalyst prepared with activated carbon alone.In addition, the polyaniline carbon support （PAnC-S）, which prepared with doping sodium dodecyl sulfate, owns lower charge transfer resistance, more mesoporous between 10～25 nm, larger specific surface area, 94.9 m2 /g.PAnC-S and PAnCh ave uniform particle sizes of ab ou t 30 nm.The Pd catal ysts prepared with PAnC-S and PAnC support have la rger electrochemical surface area, 84.7 and 62.6 m2 /g, respe ctively.Pd/PAnC-S and Pd/PAnC have higher activity and stability for for mic acid electro oxidation compared with the Pd/C.
