The removal of polychlorinated dibenzo-p-dioxins (PCDDs) via advanced oxidation processes (AOPs) poses a significant challenge due to their high toxicity and chemical stability. In this study, series well-dispersed cobalt nanoparticles supported on carbon nitrides (xCoCNs) was synthesized activate peroxymonosulfate (PMS) for 2,8-dichlorodibenzo-p-dioxin (2,8-DCDD) degradation under visible light. catalysts prepared were characterized using SEM, XPS, photoluminescence (PL), UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS). Among them, 2CoCN with an optimal Co content exhibited the highest photocatalytic efficiency, achieving 90.5% 2,8-DCDD within 160 min light/persulfate (Vis+PMS+2CoCN system). Compared other catalysts, superior optical performance narrower bandgap, enabling efficient excitation light (Vis). Notably, all xCoCNs demonstrated pH adaptability, complete neutral conditions (pH = 7) without additional acid/alkali adjustment. Through rigorous free radical capture experiments, it that SO4•−, •OH 1O2 primary reactive oxygen species (ROS) in Vis+PMS+2CoCN system. catalyst excellent reusability, stable activity retained over five cycles. Based these findings, pathways mechanisms 2CoCN+Vis+PMS system proposed. This study presents effective approach PCDD abatement wastewater treatment applications.
