Preparation of modified zirconium-based metal-organic frameworks (Zr-MOFs) supported metals and recent application in environment: A review and perspectives

In numerous types of MOFs, zirconium-based metal-organic frameworks (Zr-MOFs) were relatively new materials with high surface area, structural diversity, and tailorability, attracted extensive interest and exhibited a variety of applications, especially in adsorption, photocatalysis and catalysis. Their porosity enabled their inherent superiority in confining guest species, such as metals. Herein, this review provided significant progress in combination of metals and Zr-MOFs, including various composites of metals and Zr-MOFs, structure characteristics and applications. Special emphasis was that the review introduced applications of Zr-MOFs in removing pollutants by adsorption, photocatalysis and catalysis and explaining the corresponding mechanism. In addition, the prospects of Zr-MOFs and remaining issues had been indicated.
