Preparation of graphene and graphene supported Pd catalysts for formic acid electrooxidation

College of Chemistry and Chemical Engineering, Harbin Normal University, Harbin 150025, China

摘要

摘要: 以纳米石墨为原料，用两种方法分别制得石墨烯GN-1和GN-2。结果表明，用两种方法制备的石墨烯比表面积比纳米石墨都有显著增加。两种方法制备的石墨烯GN-1和GN-2形貌不同，孔径分布也有很大的差异。分别以两种方法制备的石墨烯为载体制备了Pd催化剂Pd/GN-1和Pd/GN-2。Pd/GN-1和Pd/GN-2催化剂的电化学比表面积分别为34.66和71.25 m²/g。这两种催化剂对甲酸的电催化氧化活性都较纳米石墨作载体制备的催化剂Pd/G有显著的提高，甲酸在Pd/GN-1和Pd/GN-2催化剂上的氧化峰电流密度分别为66.0和95.8 mA/cm²。两种催化剂对甲酸的氧化都有很好的稳定性。

Abstract: Two kinds of graphene GN-1 and GN-2 with significantly increased specific surface area were obtained from nano graphite by different methods. The morphology and pore size distribution of GN-1 and GN-2 also have great differences. Using these two kinds of graphene as supports, Pd catalysts were prepared and designed as Pd/GN-1 and Pd/GN-2. The electrochemical specific surface area of Pd/GN-1 and Pd/GN-2 catalysts are 34.66 and 71.25 m²/g. The catalytic activities of Pd/GN-1 and Pd/GN-2 during the formic acid electrooxidation reaction are greatly improved compared with the Pd catalyst supported by nano graphite. The peak current densities of formic acid oxidation on Pd/GN-1 and Pd/GN-2 are 66.0 and 95.8 mA/cm². The Pd/GN-1 and Pd/GN-2 catalysts also have good stability for formic acid electrooxidation.
