The applications of MOFs related materials in photo/electrochemical decontamination: An updated review

In recent years, metal organic framework (MOFs) related materials have attracted much attention in diversified fields, representing the vast potential for future development. In this work, we present an overview of the most recent developments in MOFs related materials for photo/electrochemical decontamination. The strategies employed for the fabrication of MOFs related materials are summarized with discussion on the application performance as well as revealing the in-depth mechanisms. The state-of-art modification strategies including heterostructure, defect engineering (e.g., oxygen vacancy and ligand defect), regulation of physicochemical properties of MOFs related materials (e.g., hydrophobicity, hydrophilcity, lewis acidity, exposed crystal face, crystallinity degree, and conjugated degree), and construction of macroscopic architecture were summarized. Also, the representative works on eletro-Fenton, electro-assisted activation, photo-electro-Fenton, photo-electrocatalysis, microbial fuel cell (MFC), capacitive deionization (CDI), urea oxidation reaction (UOR), NO3– reduction reaction (NO3RR), photocatalysis, and photo-activation are highlighted. Moreover, the effects of structural modification on the performance optimization were systematically discussed. Besides, the bibliometrics method was used to explore the hot topics and potential future development. Finally, the unsolved issues and development opportunities of MOFs related materials in the field of photo/electrochemical decontamination are proposed. It is demonstrated that the obstacles and corresponding strategies proposed in this review could accelerate further development in this promising field.
