“…The modification of porphyrin ligands mainly refers to the insertion of metal ions into the porphyrin core to form metalloporphyrin complexes [ 96 ]. After metalation, the coordination bonds are formed between the metal ion and the porphyrin ring which enhances the symmetry of the porphyrin molecule, resulting in stronger absorption in the visible and near-infrared regions and suppressed recombination of photo-generated electron-hole pairs [ 97 , 98 , 99 , 100 , 101 , 102 , 103 ]. The optical properties and catalytic activity of metalloporphyrin-based MOFs can be regulated by selecting different metal ions and controlling the structure of the porphyrin ligands.…”

Metal-organic frameworks (MOFs) are a novel category of porous crystalline materials with an exceptionally high surface area and adjustable pore structure. They possess a designable composition and can be easily functionalized with different units. Porphyrins with conjugated tetrapyrrole macrocyclic structures can absorb light from ultraviolet to visible light regions, and their structures and properties can be facilely regulated by altering their peripheral groups or central metal ions. Porphyrin-based MOFs constructed from porphyrin ligands and metal nodes combine the unique features of porphyrins and MOFs as well as overcoming their respective limitations. This paper reviewed the design and construction, light absorption and charge transfer pathways, and strategy for improving the photocatalytic performance of porphyrin-based MOFs, and highlighted the recent progress in the field of CO2 reduction, hydrogen evolution, organic synthesis, organic pollutant removal, and nitrogen fixation. The intrinsic relationships between the structure and the property of porphyrin-based MOFs received special attention, especially the relationships between the arrangements of porphyrin ligands and metal nods and the charge transfer mechanism. We attempted to provide more valuable information for the design and construction of advanced photocatalysts in the future. Finally, the challenges and future perspectives of the porphyrin-based MOFs are also discussed.

Nanohybrids (NHs) based on the conjugation of multiple carbonaceous nanomaterials and metal/metal oxides, are emerging as important photocatalysts of 21 st century and have tremendous future scopes. Overcoating one material on top of another in NHs improves performance and multifunctionality growth for a wide range of catalytic applications in organic transformations. The catalytic activity of NHs brings a phenomenal change towards various organic synthetic reactions to improve their selectivity, productivity and yield. Thus, with the background of this context, the current review covers the state of art literature up to July 2022 and brings a comprehensive discussion on the entitled subject matter. As emphasized in this review, the application of heterogeneous NHs for common organic reactions has been confirmed to be a successful tactic for the growth of extremely resourceful conversions in terms of atom economy, atom efficiency E-factor and selectivity. It also highlights the extensive and critical aspects to explore the catalytic prospects and challenges of NHs from obscurity to eminence.

“…The first approach is to mix metals or ligands by ligand-assisted exchange, postsynthetic modification, and solvothermal synthesis to increase the active center and improve photocatalytic performance. , The second approach is ligand functionalization, where it has been shown that the introduction of an amino group causes an increase in the energy of the LOMO energy level of the MOFs, thereby reducing the forbidden bandwidth . The third method is metal ion or ligand immobilization, which enhances light absorption while photogenerated electron–hole complexes are inhibited. , The fourth approach is the loading of metal nanoparticles, which is able to enhance light absorption due to the inherently porous nature of MOFs, which can accommodate nanoparticles of low Fermi energy levels within the pores or on the surface. , The fifth method is a carbon material decoration, such as carbon quantum dots (CQDs) and graphene oxide (GO) as more typical carbon materials, which can solve the problem of charge compounding while accelerating the transfer of photogenerated charges. , The sixth method is the formation of heterogeneous structures, where more active centers are created by coupling the MOF with other semiconductor materials, providing a more efficient separation of photogenerated charges . MOFs have low electronic conductivity, stability, and substrate selectivity, making them unsuitable for photocatalysis.…”

Metal−organic frameworks (MOFs) and covalent organic frameworks (COFs) are widely used in photocatalysis for their high surface area, rich pore structures, and multiple active sites. Although photogenerated carriers generated by MOFs or COFs migrate through their respective active centers under visible light, the charge recombination exists in the MOFs or COFs. Therefore, researchers have constructed covalent bonds between MOFs and COFs as migration channels to effectively mitigate charge recombination. As is well-known, an MOF-COF as a signifcant semiconductor photocatalyst is a common choice for MOFs and COFs, but no systematic analysis of MOF-COF photocatalysts is known. On the basis of our group's research, this paper provides a detailed discussion of the design, synthesis, and mechanistic analysis of MOF-COF photocatalysts. First, we discuss MOF-COF heterojunction structures that can improve the photocatalytic properties of MOFs and COFs. Further, we cover the preparation of MOF-COF photocatalysts with core−shell and non-core−shell structures that are denoted MOF@COF and MOF/COF, respectively, according to different synthesis methods. Then we analyze the mechanisms of MOF-COF photocatalysts, involving photocatalytic hydrogen evolution (PHE) and photodegradation. Finally, we discuss the challenges and opportunities of MOF-COF photocatalysts. It is hoped that this review will facilitate the development and application of MOF-COF photocatalysts.
