▎ 摘　　要

NOVELTY - Method for preparing high molecular gel Fenton catalyst, involves (a) dispersing graphene and polymer in water to obtain a dispersion liquid I, (b) dissolving iron salt and metal salt in water to obtain a metal ion solution II and (c) mixing the obtained dispersion liquid I with metal ion solution II. USE - The method is used for preparing high molecular gel Fenton catalyst such as polymer gel used in environmental governance applications (all claimed). ADVANTAGE - The method produces high-molecular gel Fenton catalyst with high catalytic activity and stability, and is easy to recover.
