Abstract
Electrochemical oxidation has attracted significant attention as an effective approach for degrading persistent organic pollutants by in-situ generating reactive oxidants. However, limitations related to mass transfer, electrode durability, and energy efficiency have motivated the development of integrated treatment strategies. This presentation discusses recent advances in coupling electrochemical oxidation with membrane separation to create multifunctional electrified membrane systems [1-6]. Key highlights include catalytic anodes designed for micropollutant degradation [4,6], hybrid electrochemical-membrane reactors for simultaneous filtration and oxidation [1,3], and electroactive nanowire membranes with improved conductivity and stability [2,5]. Continuous-flow studies demonstrate the efficient removal of organic contaminants, pathogens, and particulates, with enhanced fouling control, illustrating the potential of electrified membranes as sustainable, scalable technologies for water reuse.
