摘要
采用恒电位电化学还原技术制得石墨烯电极,然后采用循环伏安方法在石墨烯基体上电沉积一层Pt纳米微粒.采用电化学测试技术研究Pt/石墨烯电极材料的电子传递性能及对甲酸电催化氧化性能.相对于商用Pt电极材料,Pt纳米微粒/石墨烯电极材料对甲酸表现出优异的电催化氧化活性,氧化峰电流显著提高.该种石墨烯负载Pt催化剂有望用作直接甲酸燃料电池的优良电极材料.
The graphene electrode was prepared by potentiostatic electrochemical reduction technique,and a layer of Pt nanoparticles was deposited on the graphene substrate by cyclic voltammetry.The electron transfer properties of Pt/graphene electrode materials and the electrocatalytic oxidation of formic acid were studied by electrochemical testing technique.Compared with commercial Pt electrode materials,Pt nanoparticles/graphene electrode materials showed excellent electrocatalytic oxidation activity for formic acid,and the oxidation peak current was significantly increased.The graphene-supported Pt catalyst is expected to be used as an excellent electrode material for direct formic acid fuel cells.
