MIL-101(Fe)-based catalysts have been widely used for degradation of organic pollutants based on peroxymonosulfate (PMS) activation. Hence, a facile calcination and hydrothermal method was in this study to prepare MIL-101(Fe)/g-C3N4 composite catalyst with high activity stability PMS activation degrade tetracycline hydrochloride (TC) under visible-light irradiation. We clearly elucidated the mechanism involved photo Fenton-catalyzed process by separating pollutant oxidation processes. The synergetic effects MIL-101(Fe) g-C3N4 acting as an electron shuttle mediating transfer from substrate PMS, accompanied redox cycling surface Fe(II)/Fe(III). Multiple experimental results indicated that bound during visible irradiation generation sulfate radicals (SO4•-), hydroxyl (•OH) superoxide anion free (•O2-) radical pathway singlet oxygen (1O2) holes (h+) nonradical pathway. major pathways TC can be described demethylation, deamination, deamidation carbonylation. This work provides valuable information advances fundamental understanding needed design syntheses metal-free conjugated polymers modified metal-organic frameworks heterogeneous photo-Fenton reactions.
