Beschreibung
Zusammenfassung:	The invention relates to a reducing-oxidized graphene/amorphous carbon composite material loading Cu/Cu2O photocatalyst as well as a preparation method and application of the composite material. The preparation method of the composite material comprises the following steps: by taking oxidized graphene, glucose or polysaccharide as carbon sources, preparing a reduction-oxidized graphene/amorphous carbon substrate dispersion agent by adopting hydro-thermal synthesis, and then directly adding soluble copper salt into the dispersion agent, so as to further prepare the reducing-oxidized graphene/amorphous carbon composite material loading the Cu/Cu2O photocatalyst by adopting hydro-thermal synthesis. For the obtained composite material, spherical Cu/Cu2O photocatalyst grows on a lamellar reducing-oxidized graphene/amorphous carbon substrate, the reducing-oxidized graphene/amorphous carbon substrate has good hydrophilia, can increase adsorption of Cu/Cu2O photocatalyst on organic pollutants in water body, and can further improve the photocatalytic performance of the Cu/Cu2O photocatalyst, and has great significance on water treatment for purifying organic pollutants in water.
