摘　　要：采用纳米石墨为原料,以3种不同还原温度80,60和40℃分别制得石墨烯GN-1、GN-2和GN-3。用3种不同还原温度制备的石墨烯作为载体制备了Pd催化剂Pd/GN-1、Pd/GN-2和Pd/GN-3。发现这3种钯催化剂Pd/GN-1、Pd/GN-2和Pd/GN-3中,Pd/GN-1具有最大的电化学比表面积,对甲酸的电催化氧化活性也最高,而Pd/GN-2电催化剂对甲酸电催化氧化的稳定性最好。The graphene GN-1, GN-2 and GN-3 were prepared respectively with nanographite as raw meterials in three different reduction temperature of 80,60 and 40℃. Then Pd catalyst Pd/GN-1, Pd/GN-2 nad Pd/GN-3 were prepared by the three graphene. It was found that Pd/GN-1 has largest specific area, highest electro catalytic oxidation activity on formic acid. Pd/GN-2 has best electrochemical oxidation stability on formic acid.
