A new FeOCl/graphene quantum dot catalyst for peroxymonosulfate activation to efficiently remove organic pollutants and inactivate Escherichia coli

Abstract

The sulfate radical-based advanced oxidation processes (SR-AOPs) are well-established and efficient techniques for degradation of organic pollutants. Fe2+ is used as an environmentally friendly and cost-effective catalyst for activating peroxymonosulfate...

Iron pyrophosphate doped carbon nanocomposite for tetracycline degradation by activation of peroxymonosulfate

“…24 Pure Fe cannot achieve an optimal removal efficiency, so heteroatom doping is used to improve the catalytic ability. 25 Transition metal phosphates, such as iron phosphates are of great interest due to their low cost, abundance of earth resources, environmental friendliness, and good stability, which have been used in electrocatalysis. 26,27 The divalent pyrophosphate, as a kind of phosphate, has been shown to not only act as a proton receptor to ensure the stability of the catalyst but also to induce structural distortions in the transition metals, thus facilitating the adsorption between the material and the contaminant.…”
