▎ 摘　　要

NOVELTY - Preparing electro-fenton composite film cathode comprises uniformly dispersing nano-particles of a heterogeneous iron-containing catalyst in an electrostatic spinning solution. An electrostatic fiber is collected on a conductive carbon material carrier for producing hydrogen peroxide. Nano-particles form an electro-spinning catalytic film along with an electrostatic fiber generating process. The electro-spinning catalytic film is loaded on the carrier. The heterogeneous iron-containing catalyst is nano-ferroferric oxide, iron powder and/or ferric oxide. The carbon material is activated carbon fiber, carbon sponge and/or carbon felt, preferably modified carbon felt. The method utilizes dimethylformamide, sodium dodecyl sulfate, polyvinylidene fluoride, acetone, deionized water, graphene, carbon black and polytetrafluoroethylene to prepare electro-fenton composite film cathode. USE - The method is useful for preparing electro-fenton composite film cathode, which is useful for processing micro-pollutants (all claimed). ADVANTAGE - The method can obviously improve yield of hydrogen peroxide, especially in electrostatic fiber generating process. Graphene and carbon black modified carbon felt with good conductivity is utilized as fiber receiving device. Hydrogen peroxide is generated in situ at modified carbon felt interface with high efficiency. Hydroxy group is generated in situ at nano-particle catalytic interface. The yield of hydrogen peroxide is greatly improved. The micro-pollutant enriched on surface of film cathode is effectively catalyzed, so as to realize efficient removal of micro-pollutant. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) electro-fenton composite film cathode, prepared by above method; and (2) processing micro-pollutant.
