| 摘 要： | 应用Hummers法氧化合成氧化石墨(GO), 然后用化学一步还原法制得石墨烯（graphene）负载Pd催化剂. 用同样方法以多壁碳纳米管（MWCNTs）、单壁碳纳米管（SWCNTs）和Vulcan XC-72为载体制备了不同负载型的Pd催化剂. X射线衍射(XRD)、透射电镜(TEM)表征表明,在石墨烯载体上Pd纳米粒子粒径较小，且分布均匀. 电化学活性面积(ECSA)、循环伏安(CV)、计时电流(CA)和计时电位(CP)电化学测试显示, 与其它3种碳载体的Pd催化剂相比, 石墨烯负载Pd催化剂对甲酸电催化氧化的催化活性和稳定性最好.

| Abstract: | Graphite oxide(GO) was prepared by Hummers method.Then the graphene nanosheets supporting Pd catalysts were prepared by a single-step chemical reduction method.The electrocatalytic performance for formic acid oxidation of the prepared Pd/graphene composite was studied as an electrode material in comparison with the composite catalysts based on the other carbons(MWCNTs,SWCNTs,and Vulcan XC-72 carbon black).X-ray diffraction(XRD) and transmission electron microscopy(TEM) measurements indicated that the Pd nan... |
