Oxidation of tetracycline hydrochloride with a photoenhanced MIL-101(Fe)/g-C3N4/PMS system: Synergetic effects and radical/nonradical pathways

Sulfate Radical-Based Degradation of Organic Pollutants: A Review on Application of Metal-Organic Frameworks as Catalysts

“…The high concentration of active Fe sites and the sizable surface area of the MOF are responsible for MIL-101(Fe) catalytic activity. 21 It has been concluded that the synergistic effect between g-C 3 N 4 and MIL-101(Fe) significantly increases in the presence of light, and the catalyst was structurally stable during the reaction, as the ratio of Fe precursor in the catalyst was same before and after the process. 21 The PMS decomposition in an acidic environment provides excessive production of SO 4…”

“…127 • Synergistic effects: MOFs and PS/PMS enhance the degradation efficiency by providing additional catalytic sites, stabilizing reactive species, and promoting efficient contaminant degradation through cooperative interactions. 21,108 • Selectivity and contaminant removal: MOFs exhibit selectivity in degradation studies, preferring specific contaminants over others, enabling targeted degradation in complex mixtures and removing problematic compounds. Therefore, the choice of the MOF in degradation studies should be carefully considered to optimize the interaction and enhance the overall degradation performance.…”

“… Catalytic reactions: MOFs activate PS/PMS by decomposing metal centers, generating reactive radicals like SO 4 •– that degrade contaminants and enhance activation efficiency. , Surface reactions: Surface reactions on the MOF material involve activated PS or PMS species reacting with contaminants, causing surface-mediated degradation through electron transfer, radical attack, or oxidative processes Synergistic effects: MOFs and PS/PMS enhance the degradation efficiency by providing additional catalytic sites, stabilizing reactive species, and promoting efficient contaminant degradation through cooperative interactions. , Selectivity and contaminant removal: MOFs exhibit selectivity in degradation studies, preferring specific contaminants over others, enabling targeted degradation in complex mixtures and removing problematic compounds. …”

Role of Interface of Metal–Organic Frameworks and Their Composites in Persulfate-Based Advanced Oxidation Process for Water Purification

“…All the generated ROS and the photogenerated h + contributed to the degradation of pollutants. An excellent photo-Fenton catalyst MIL-101(Fe)/g-C 3 N 4 composite was constructed combined with a g-C 3 N 4 semiconductor 101. Different antibiotics such as TC, oxytetracycline (OTC), and CIP were efficiently degraded by the MIL-101(Fe)/g-C 3 N 4 / PMS system with high TOC removal rates of 88.9%, 85.7%, and 62.1%, respectively.…”
