In this work, the CoP/NF successfully was synthesized to tune PMS activation from a radical pathway to a non-radical dominated pathway for efficient degradation of organic pollutants. The incorporation of phosphorus element modulated the cobalt-based catalyst surface charge state and induced local charge density, facilitating the catalytic activity. Consequently, at optimal conditions (catalyst = 1.5 cm2, PMS = 0.3 g/L), CoP/NF achieved nearly complete removal of 40 mg/L rhodamine B (RhB) within 2 min over a wide pH (3.0–9.0), and maintained a strong anti-interference capacity for NO3−, PO42−, Cl−. Furthermore, the degradation efficiency of RhB in the CoP/NF + PMS system remained 98 % even after 5 cycles. Impressively, ROS trapping and electron spin resonance (EPR) analyses revealed that the degradation process was dominantly driven by superoxide radicals (O2•–) and singlet oxygen (1O2), which served as the key mechanism for the CoP/NF + PMS system.
