Abstract

Advanced oxidation processes (AOPs) based on activation of peroxymonosulfate (PMS) to generate sulfate radicals have been extensively studied in the removal of organic pollutants in water. In this work, we prepared a Fe, Co activated and N, P co-doped carbon nanofiber catalyst named as Fe/Co-N/P-9 (carbonized at 900 °C) for the activation of PMS via the combination of porous metal–organic frameworks (MOF) materials with 1D carbon nanofibers. Graphite carbon nanofibers provided good electrical conductivity. Fe and Co could be used as catalytic active sites. Heteroatoms modified electronegativity of adjacent carbon for the adsorption of PMS. Sugar-coated haws stick structure provided large contact area and mass transfer channel, and the metal protected by graphite carbon layer improved the stability. Owing to the above advantages, the catalyst showed good performance for the degradation of rhodamine B (RhB) and the applicability of the catalyst under different conditions was also systematically studied. Radical quenching experiments and electron paramagnetic resonance (EPR) confirmed that both sulfate radicals (SO4–•) and hydroxyl radicals (·OH) existed in the system. This work provides a practiced idea for the preparation of efficient PMS activation catalysts.
