▎ 摘　　要

NOVELTY - Magnetic graphene-loaded photocatalyst comprises magnetic graphene carrier and photocatalyst loaded on it. USE - The photocatalyst is useful in sewage treatment including domestic sewage including black and smelly water (all claimed). ADVANTAGE - The photocatalyst: has large specific surface area, strong synergistic effect, excellent adsorption and conductivity; method: inhibits the recombination of photogenerated electron-hole pairs generated during the photocatalytic process; increases the adsorption of pollutants by the photocatalyst; enhances the catalytic performance of the photocatalyst; solves the problem of photocatalyst recovery; and removes the magnetic adsorption of the metal ion. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM is also included for preparing magnetic graphene-loaded photocatalyst comprising adding photocatalyst into the magnetic graphene solution, reacting, drying and calcining to obtain magnetic graphene-loaded photocatalyst.
