The presence of micropollutants in water bodies pose threaten to human health and advanced strategies are urgently needed to deal with this challenging issue. The usage of permanganate (KMnO4) to decompose micropollutants is a promising option, however, the poor reaction kinetics and low KMnO4 utilization efficiency yet to be resolved. Herein, we rationally designed a catalytic carbon nanotube (CNT) membrane for KMnO4 activation toward enhanced degradation of micropollutants. The proposed fluidic system outperformed conventional batch reactor owing to the improved mass transfer via convection and improved KMnO4 utilization. The underlying electron transfer mechanism was unveiled by integrating solid experimental evidences and theoretical calculations. The outcome of this study is dedicated to provide a viable and effective route for rapid decontamination of micropollutants from water.
