▎ 摘　　要

NOVELTY - Preparing three-dimensional graphene-based electric Fenton cathode involves wet spinning liquid crystal phase graphene oxide dispersion liquid, obtaining graphene oxide fibers through a coagulation bath, assembling and reducing the graphene oxide fiber to obtain the three-dimensional graphene-based electric Fenton cathode. USE - Method for preparing three-dimensional graphene-based electric Fenton cathode used in the organic wastewater treatment (claimed). ADVANTAGE - The method has good conductivity, large specific surface area, rich catalytic activity site, and has wide application prospect.
