| titleOfInvention | Preparation and regeneration method of iron-complexing type carbon film electro-Fenton cathode |
| abstract | The invention relates to a preparation and regeneration method of an iron-complexing type carbon film gas diffusion electrode applied to an electric Fenton system. The preparation is prepared from the following components: the preparation method comprises the following steps of nitrogen-doped graphitized carbon nanotubes, graphene oxide dispersion liquid, sodium hydroxide, ferrous sulfate heptahydrate, polytetrafluoroethylene emulsion, absolute ethyl alcohol, acetone, deionized water, oxygen and nitrogen. The preparation method comprises the following steps: (1) preparing iron complex graphene oxide powder (2) preparing an iron complex type carbon film gas diffusion electrode. The electrode regeneration method comprises the following steps: and (3) arranging the gas diffusion electrode in a reactor, introducing nitrogen, putting electrolyte into the reactor, carrying out electro-reduction regeneration under a constant cathode potential, washing the regenerated electrode with deionized water, and drying. The gas diffusion electrode plays the role of a cathode in the reactor, and O is finished in sequence according to the air flow direction 2 Catalytic reduction and OH generation reaction, and gas distribution effect, and promotes mass transfer in the liquid phase region. The performance of the regenerated electrode is substantially unchanged compared to the new electrode. |
