▎ 摘　　要

NOVELTY - Preparing spherical shell-shaped three-dimensional graphene comprises (i) uniformly mixing copper(ii) sulfate, nickel(ii) sulfate and sulfuric acid by transferring into a ball crystallization accelerator; (ii) washing the step (i) product reputedly with ultrapure water, filtering and freeze drying; and (iii) placing the lyophilized sample in a vacuum oven, carrying out first reduction treatment in a hydrogen atmosphere, carrying out graphene deposition process at a high temperature in a mixed atmosphere of hydrogen and methane and removing metal substrate. USE - The method is useful for preparing spherical shell-shaped three-dimensional graphene (claimed). ADVANTAGE - The method has simple operation. The product has good catalyzing effect. DETAILED DESCRIPTION - Preparing spherical shell-shaped three-dimensional graphene comprises (i) uniformly mixing copper(ii) sulfate, nickel(ii) sulfate and sulfuric acid by transferring into a ball crystallization accelerator, depositing the mixed solution on the copper sheet working electrode, where the sheet comprises copper or copper-nickel cluster, to obtain mixed solution deposited on the sheet; (ii) washing the step (i) product reputedly with ultrapure water, filtering and freeze drying; and (iii) placing the lyophilized sample in a vacuum oven, carrying out first reduction treatment in a hydrogen atmosphere, carrying out graphene deposition process at a high temperature in a mixed atmosphere of hydrogen and methane and removing metal substrate using ammonium persulfate solution or ferric trichloride solution, to obtain the final product.
