Abstract

En 中文

• MnCo2O4 was innovatively and stably loaded onto a solid-waste-based CM to construct a catalytic-filtration system. • Systematically investigated membrane fouling performance across different filtration systems. • MnCo2O4/CM-PMS enables efficient humic acid degradation and flux recovery. • EPR and DFT reveal 1O2-dominated non-radical and radical synergistic degradation. • High removal efficiency and stable recyclability in real and antibiotic-contaminated water.
