▎ 摘  要

NOVELTY - A graphene composite aerogel comprises graphene aerogel-supported iron silicate composite particles as core material and nano-ceramic powder that form three-dimensional network structure. The composite material has porosity of 80-93%. The nano-ceramic powder has particle diameter of 10-100 nm. USE - Graphene composite aerogel used as ozone oxidation catalyst for processing sewage. ADVANTAGE - The graphene composite aerogel has improved adsorption capacity, and improves the purification efficiency of sewage. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of graphene composite aerogel, which involves mixing graphene aerogel and silicon source solution, adding iron source, carrying out hydrothermal reaction, taking out gel, drying, crushing, adding nano-ceramic powder, impregnating in organic solvent to obtain slurry, stirring in high-speed, soaking porous polymer template is immersed in slurry, sintering at 700-890 degrees C, calcining to remove template, washing and drying.
