▎ 摘  要

NOVELTY - Method for preparing graphene aerogel-loaded catalyst material, involves (a) preparing a graphene oxide dispersion, (b) mixing the metal material and antimony trioxide powder, adding nitric acid, heating, stirring, placing the solution in an ice-water bath, slowly dripping hydrogen peroxide, adding ultrapure water for hydrothermal reaction, separating the solid, and drying to a obtain nano metal oxide catalyst, and (c) dissolving the obtained catalyst in ultrapure water using amine as a co-solvent, adding the obtained mixed solution to the graphene oxide dispersion, subjecting the mixture to the hydrothermal reaction to obtain a graphene aerogel loaded with the nano metal oxide catalyst, freezing, and drying to obtain the catalyst. USE - The method is useful for preparing graphene aerogel-loaded catalyst material used as a photocatalyst and an adsorbent (all claimed). ADVANTAGE - The prepared catalyst material ensures excellent adsorption of pollutants and excellent degradation ability of pollutants, and exhibits synergistic effect of adsorption and photocatalysis.
