▎ 摘  要

NOVELTY - Preparing non-metallic three-dimensional macroscopic structured graphene-organic aerosol photocatalyst, comprises (i) mixing graphene oxide, water and organic eosin ultrasonically, and carrying out hydrothermal treatment at 120-200 degrees C for 6-48 hours to obtain hydrophilic three-dimensional graphene-organic solid, and (ii) freeze-drying the obtained solid to obtain final product. USE - The photocatalyst is useful for: selective hydrogenation of aromatic nitro compound (4-nitroaniline, 4-nitrophenol, 4-nitroanisole, 6-nitrophenol or 6-nitroaniline) to corresponding aromatic amine compound in aqueous phase under visible light; and catalytic reduction to remove hexavalent chromium in contaminants under visible light (all claimed). ADVANTAGE - The method: utilizes easily available raw materials; has simple operation and low cost; and is environmentally friendly.
