▎ 摘　　要

NOVELTY - The preparation of graphene-zinc oxide three-dimensional porous composite material, involves (1) mixing graphene oxide, reducing sugar, zinc salt and a solvent to obtain a dispersion liquid, and (2) adjusting the pH of the dispersion obtained in step (1), and then heating and cooling. USE - Preparation of graphene-zinc oxide three-dimensional porous composite material used in sewage treatment (all claimed). ADVANTAGE - The graphene zinc oxide three-dimensional porous composite material has relatively high specific surface area, effectively prevent the stacking of graphene sheets, and has a good adsorption effect on heavy metal ions.
