A Potential Roadmap to Integrated Metal Organic Framework Artificial Photosynthetic Arrays

Abstract

Metal organic frameworks (MOFs), a class of coordination polymers, gained popularity in the late 1990s with the efforts of Omar Yaghi, Richard Robson, Susumu Kitagawa, and others. The intrinsic porosity of MOFs made them a clear platform for gas storage and separation. Indeed, these applications have dominated the vast literature in MOF synthesis, characterization, and applications. However, even in those early years, there were hints to more advanced applications in light-MOF interactions and catalysis. This perspective focuses on the combination of both light–MOF interactions and catalysis: MOF artificial photosynthetic assemblies. Light absorption, charge transport, H2O oxidation, and CO2 reduction have all been previously observed in MOFs; however, work toward a fully MOF-based approach to artificial photosynthesis remains out of reach. Discussed here are the current limitations with MOF-based approaches: diffusion through the framework, selectivity toward high value products, lack of integrated studies, and stability. These topics provide a roadmap for the future development of fully integrated MOF-based assemblies for artificial photosynthesis.

Development of MOF Based Recyclable Photocatalyst for the Removal of Different Organic Dye Pollutants

“…Industries all over the planet produce wastewater in huge amounts which contains wastes mainly of organic and inorganic mixtures. The inadequate treatment of all of these wastes poses a serious threat to human health and the quality of water bodies [ 4 , 5 ]. Particularly, organic pollutants are very difficult to degrade, and extremely toxic [ 6 , 7 ].…”

Polypyridyl Ru(ii) or cyclometalated Ir(iii) functionalized architectures for photocatalysis

“…In the past two decades, well-defined architectures of MOFs, [9][10][11][12] COFs, [13][14][15] metallasupramolecules, [16][17][18] organic supramolecules [19][20][21] and SOFs [22][23][24][25] have received greater attention due to their rich and designable structures, modifiable pore space and tunable functionality. 26 These architectures provide the best models for the structure-property relationship study, and the well-organized skeletons commonly possess special functions for olefin separation in hierarchical porous MOFs 27,28 for enzyme separation in mesoporous COFs, 29,30 for unusual reactions in metallasupramolecules which act as molecular flasks, 31 for photodynamic therapy efficacy in organic supramolecules 32 and for accessible film production in SOFs.…”

Thermocatalytic Conversion of CO2 to Valuable Products Activated by Noble‐Metal‐Free Metal‐Organic Frameworks

“…Metal‐organic frameworks (MOFs), a class of new catalysts that constructed from metal ions/clusters and organic ligands through coordination bonds, have attracted much attention in the field of catalysis [19–41] . Many important researches focused on hydrogenation, [42–45] reduction, [46–51] cycloaddition, [52–56] carboxylation, [57–59] and coupling reactions [60–63] have been reported in recent years.…”
