▎ 摘　　要

NOVELTY - Preparation of a three-dimensional adsorption-enhanced electric Fenton cathode material has a heterogeneous sandwich structure, including external layer and intermediate layer having complementary and synergistic advantages on each layer. The outer two layers are iron-based porous carbon fiber composite layers. The intermediate layer is composed of a gas diffusion layer containing low-dimensional carbon materials and a cerium-based porous carbon fiber composite layers are interwoven. USE - The method is used for preparing three-dimensional adsorption-enhanced electric Fenton cathode material. ADVANTAGE - The cathode material effectively avoids the problem caused by the lack of catalytic sites due to the excessive use of binders and conductive agents, improve the performance of hydrogen peroxide electro-forming, and has a good adsorption and enrichment effect to the pollutants in the water body.
