摘　　要：采用处理与未处理的活性炭制备Pd/C催化剂,运用循环伏安法(CV)和计时电流法检测两种Pd/C催化剂对甲酸的电催化氧化活性和稳定性.通过透射电镜(TEM)对催化剂进行了表征.结果表明,用硝酸处理的活性炭所制备的Pd/C催化剂中Pd粒子的分散更均匀,对甲酸的电催化氧化活性和稳定性都有不同程度的提高.Two Pd/C catalysts were prepaid by two kinds of activated carbon. One carbon is treated by HNO3 and the other without the treatment. The catalysts prepared have been characterized by cyclic vohammetry, chronoamperometry techniques, and transmission electron microscopy（TEM）. The results showed that Pd/C with the treated carbon support had higher electrocatalytic oxidation activity and stability.
