Abstract

Abstract: In this study, a Fe, N-decorated carbocatalyst (FeCN@X) based on Fe-MOFs was synthesized to activate peroxydisulfate (PDS) for removing sulfadiazine (SDZ) from water. The surface morphology and structure of FeCN@X was characterized by scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spec troscopy. FeCN@1000, formed at the pyrolysis temperature of 1000 ℃, exhibited the best catalytic performance for degrade SDZ in the presence of 0.15 g·L^-1 catalyst and 0.5 mmol·L^-1 PDS, and the reaction conversion rate was 0.199 L·mmol^-1. Moreover, the effects of experimental conditions, co-existing anions and fulvic acid on catalytic performance of FeCN@1000 were investigated. The excellent potential of FeCN@1000 as a PDS activator in environmental applications was also suggested by the results of its reusability and adaptability experiments. The result of XPS, ROS quenching, EPR and electrochemical experiments showed the degradation of SDZ was primarily driven by an electron transfer process (ETP). Furthermore, Fe(III) instead of Fe(II) plays a major role in ETP, as Fe(III) sites can interact with PDS and form the low-spin surface complexes (Fe(III)/CN-PDS). Meanwhile, the small number of ¹O₂ and O₂^-· generated by the activation of PDS will promote the system degradation of SDZ activity by accelerating the conversion of Fe(II) to Fe(III). This study provides new insights for the design of novel PDS activator for efficient degradation of emerging pollutants by ETP.
