▎ 摘 要
NOVELTY - Preparing three-dimensional copper oxide graphene comprises (1) dispersing, dissolving graphene oxide, and adding aqueous ammonia to adjust the pH of the solution to 11-12, (2) adding copper nitrate to the solution to obtain a mixed solution, and (3) subjecting the mixed solution to a hydrothermal reaction, and freeze-drying the product obtained from the reaction to obtain a three-dimensional copper oxide graphene material. USE - The method is useful for preparing three-dimensional copper oxide graphene, which is useful in the degradation of antibiotics by activating persulfate (claimed). ADVANTAGE - The method: is a simple; promotes the catalytic decomposition of antibiotics by catalyst; and has good use value. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a use method of three-dimensional copper oxide graphene comprising using three-dimensional copper oxide graphene to adsorb the antibiotic to be degraded, and then adding persulfate for the degradation reaction. (1) a three-dimensional copper oxide graphene; and
