摘要
采用纳米石墨为原料,硼氢化钠作为还原剂制得石墨烯载体GN,并制备钯催化剂Pd/GN.将催化剂均匀的涂抹在碳纸上制备工作电极后,一种采用电极处理Pd/GN-1,另一种不采用任何处理Pd/GN-2.发现采用电极处理制备的石墨烯载Pd催化剂电极对甲酸氧化阳极催化活性和稳定性有很大的提高.
The graphene GN from Nano graphite is obtained by sodium NaBH4 as reducing agent, and with this kind of graphene as a supporter, Pd catalyst was prepared and designed as Pd,/GN. By spread evenly prepared a catalyst in the preparation of the working electrode on carbon paper and then one use electrode process of treatment Pd/GN - 1, another does not use any treatment Pd/GN - 2. Preparation of electrode process treatment palladium catalyst Pd/GN - 1 than Pd/GN - 2 for formic acid electrooxidation have greatly improved and a good stability.
