Abstract

The invention aims to provide a preparation method for a nickel / graphene nanometer compound material, which is simple in operation, high in yield and uniform in dispersion of metallic nanometer particles on a graphene surface. According to the preparation method, dimethylglyoxime and nickel salt are taken as raw materials for preparing nickel dimethylglyoxime, and the decomposition reaction is performed on the nickel dimethylglyoxime at high temperature, thereby acquiring the nickel / graphene nanometer compound material. The preparation method comprises the following steps: weighting the dimethylglyoxime and the nickel salt; placing the nickel salt into deionized water, and placing the dimethylglyoxime into absolute ethyl alcohol and then adding aqueous ammonia; filtering the nickel dimethylglyoxime acquired by uniformly mixing the two solutions, washing the nickel dimethylglyoxime with the deionized water and drying; and performing the decomposition reaction on the dried nickel dimethylglyoxime at high temperature, thereby acquiring the nickel / graphene nanometer compound material.

Description

technical field [0001] The invention belongs to the field of inorganic nanocomposite materials, in particular to a preparation method of nickel / graphene nanocomposite materials. Background technique [0002] Graphene was first successfully prepared by scientists from the University of Manchester in 2004.
