This article provides an in-depth overview of the state-of-the-art metal-organic frameworks (MOFs)-based materials for sulfate radical-based advanced oxidation processes (SR-AOPs) applications, summarizing synthetic strategies, applications in wastewater treatment, and theoretical calculations to predict reaction mechanisms. Special emphasis is placed on the effects of structure on catalytic activities and the circumstances of radical and non-radical reaction mechanisms in MOFs-based SR-AOPs. Future research directions and unresolved challenges are also discussed.
Recently, metal-organic frameworks (MOFs) based materials as the emerging catalysts for sulfate radical-based advanced oxidation processes (SR-AOPs) applications have progressively become a burgeoning research field. Herein, an in-depth overview of state-of-the-art MOFs-based materials currently available in SR-AOPs applications for environmental remediation is presented. The synthetic strategies of different types of MOFs-based materials are summarized. Most importantly, particular emphasis is placed on the applications of MOFs-based materials in SR-AOPs for wastewater treatment. Identification of reactive oxygen species (ROS) generated from the radical and non-radical pathways is addressed. Moreover, the theoretical calculations based on density functional theory (DFT) to predict and explore the possible reaction mechanisms in MOFs-based SR-AOPs are summarized and discussed. Special attention has been focused on the effects of structure on the catalytic activities and the circumstance of radical and non-radical reaction mechanisms in MOFs-based SR-AOPs. Finally, the unresolved challenges of the existent MOFs-based SR-AOPs are pointed out and the outlooks of future research directions are proposed.
