Optimal preparation of catalytic Metal-organic framework derivatives and their efficient application in advanced oxidation processes

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.

Automated summary

Metal-organic frameworks (MOFs) derivatives show excellent user-configuration flexibility and improved stability, conductivity, and inherited characteristics after pyrolysis. Although the synthetic method of MOF derivatives is relatively rough, they are gradually being proven as potential alternative catalysts in advanced oxidation processes (AOPs).
