摘要：

为了提高Pd/C催化剂对甲酸电化学氧化的电催化性能和降低催化剂的成本,以XC-72碳为载体,通过金属置换反应制备中空结构的Pd/C催化剂,并用X-射线衍射（XRD）,透射电镜（TEM）和X-射线电子散射能谱（EDX）对催化剂微观形貌和结构进行表征.结果显示中空Pd纳米粒子的平均直径为27.3 nm, 电化学活性比表面积为116 m2/g,远远高于用硼氢化钾还原制备的实心Pd/C催化剂的.中空的Pd/C催化剂对甲酸氧化的电催化活性显著高于实心Pd/C催化剂,同时中空Pd/C催化剂的催化活性稳定性也优于实心Pd/C催化剂.
Abstract:

In order to improved the electrocatalytic performances of Pd/C catalysts for formic acid oxidation and low the catalyst cost, hollow Pd catalyst supported on carbon XC-72 was prepared by a metal replacement reaction at room temperature. The catalysts were characterized by TEM, XRD and EDX. The average diameter of hollow Pd nanospheres was 27.3 nm and the electrochemical active surface area of hollow Pd nanospheres is 116 m2/g, which is much higher than that of solid Pd/C catalyst prepared by employing KBH4 as reducing agent. Electrochemical tests show that the hollow Pd/C catalyst displays much higher electrocatalytic activity and the better stability for formic acid oxidation than the solid Pd/C electrocatalyst．
