Decolorizations,degradation and mineralization of wastewater containing dyes utilizing an electrocatalytic membrane reactor(ECMR)is a beneficial development to conventional advanced oxidation processes(AOPs)caused of its robust efficiency and sustainability and environmental appropriateness.We herein developed a stainless-steel mesh(SSM)electrode supported a porous membrane via incorporation of a PVDF casting solution containing CuFeO2 delafossite nanoparticles impregnated in nanoporous carbon(NPG)biomass derived from apple powder as a critical electrocatalytic and chemical confinement active sites.The SSM membrane electrode was applied as the anode in a gravity-driven ECMR with deep-permeation and self-cleaning function and its concept-of-proof were investigated by methyl orange(MO,as typical azo dyes)electrocatalytic oxidation/filtration.As-designed system exhibiting a robust degradation efficiency of over 98.72% toward MO due to the heterointerfacial structure of CuFeO2 and NPC,which provided the fast electron transfer and low recombination rate,the superior generation rate of the hydroxyl radicals,large effective surface area,self-regenerability,and the least fouling and concentration polarization.The TOC and COD analysis validated that the treatment by as-prepared ECM is proficient for effluent-treatment than the industrial physico-chemical treatments.This strategy beacon paves the headlight for the substantial understanding and designing of novel extremely effective and economic ECMs for several potential applications,including environmental remediation.
