▎ 摘　　要

Graphene oxide (GO) was synthesized by a modified method. The different nickel plating graphene samples with diverse amount of nickel plating are synthesized by a novel method. The three-electrode system electrochemical workstation (CHI670) is used to test the electrochemical property through the cyclic voltammetry curve and time current curve. The samples' surface morphology is characterized respectively by the scanning electron microscope (SEM) and transmission electron microscope (TEM). The sol-gel method made distinct deep color surface layer growth tightly on original sheets. When the NiSO4 center dot 6H(2)O involved in the reaction was 0.65 g, the samples demonstrated superior catalytic activity in comparison to other concentrations. In 0.1 M NaOH electrolyte solution, methanol oxidation peak occurred at around 0.7 V with a higher and relatively stable electric current value. The most suitable loading quantity exhibited superior electro-catalytic performance.
