Abstract

Metal-organic frameworks (MOFs) have been widely concerned for their excellent user-configuration flexibility to be capable of different tasks. A popular trend of their diversified development is pyrolyzing them to produce derived materials with improved stability, conductivity, and well-inherited characteristics. Thanks to these properties, prepared MOF derivatives are gradually testified as alternative catalysts in advanced oxidation processes (AOPs), involving Fenton reaction, sulfate radical-based AOPs (SR-AOPs) as well as photocatalysis for efficient pollutants degradation. Unfortunately, the introduction of the synthetic method of MOF derivatives is relatively rough yet and a comprehensive understanding of the differences in their application to different AOPs systems has not emerged. This review creatively details synthetic strategies of MOF derivatives by analyzing their special conditions and procedures. And starting with suitable MOF precursors, the review focuses on their changes in structure and component during derivation and associates them with performance improvements in AOPs. Besides, the related mechanisms are also discussed respectively by distinguishing the functional sites in different systems. • The review details pyrolysis synthesis methods of MOF derivatives. • Different classes of MOF precursors available to be applied in AOPs are summarized. • The change of physical-chemical properties is associated with the improvement of performance. • Catalytic mechanism of MOF derivatives in individual advanced oxidation systems. • Future outlook and challenges for MOF derivatives based AOPs.
