石墨烯的制备及石墨烯载Pd催化剂对甲酸的电催化氧化
Preparation of graphene and graphene supported Pd catalysts for formic acid electrooxidation
摘要
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.关键词
