摘要：Using nitrate saturated metal-organic frameworks (MOFs) MIL-101-NH2(Fe) as precursors, N, O co-doped carbon/Fe composites (NOC/Fe-MIL) were synthesized by carbonization for activating peroxymonosulfate (PMS) to degrade sulfadiazine (SDZ). N and O species were doped into the carbon matrix by adsorbed nitrate, increasing the degradation rate of SDZ by 2.80 times compared to the original materials (NC/Fe-MIL). N, O co-doping not only increased the charge transfer rate on the materials surface, but also provided more pyridine N, C=O groups and defects as main active sites for enhancing the adsorption to PMS indicated by DFT calculations, thus promoting the generation of O-2(center dot-) and O-1(2) to degrade SDZ. More importantly, the NOC/Fe-MIL/PMS system still exhibited stable degradation performance in a wide pH range and in the presence of background anions, which can be used in a variety of complex water matrices and regenerated by heating, enabling it to be applied to practical wastewater treatment. This work will provide a general approach for preparing heteroatom modified materials and new insights for exploring critical roles of N and O species in PMS activation.
