MOF-based In2S3-X2S3 (X = Bi; Sb)@TFPT-COFs hybrid materials for enhanced photocatalytic performance under visible light

Hybrid Porous Crystalline Materials from Metal Organic Frameworks and Covalent Organic Frameworks

“…Many postsynthetic modification strategies of imine‐based COFs have been realized, [ 171 , 172 ] which, when successfully incorporated in MOF/COF hybrids, will open the door to further improve the physical and chemical properties. Non‐imine based COFs, such as the triazine‐based aromatic frameworks [ 83 , 87 , 90 ] and the sp 2 carbon‐based conjugated COFs, [ 173 , 174 , 175 ] will provide access to a unique class of semiconducting hybrid materials with tunable optical and electronic band gaps. In addition, the MOF/COF hybrids are mainly focused on using 2D COFs, with only two exceptions where 3D COFs were incorporated in the MOF/COF composite membrane.…”

“…When used as a heterogeneous catalyst for the oxidation of styrene, the hybrid has shown significantly enhanced conversion and selectivity toward the formation of benzaldehyde. Similarly, several other new MOF/COF hybrid materials have been developed successively using this one‐pot strategy, such as the MOF/TFPT‐TFPA by Cai and coworkers, [ 83 ] MOF‐based In 2 S 3 ‐X 2 S 3 (X = Bi; Sb)/TFPT‐COFs by Wang and coworkers, [ 87 ] MOF‐5/M5C by Dashtian and coworkers, [ 91 ] and Fe 3 O 4 /MOF UiO‐66 /TzDa‐COF by Xu and coworkers. [ 98 ] These functional heterostructured hybrids have been used for photodegradation or as adsorbents of environmental pollutants, as discussed in later sections.…”

“…The doped hybrid also showed impressive long‐term stability and recycling stability. They further developed analogous MOF‐based In 2 S 3 ‐X 2 S 3 (X = Bi; Sb)/TFPT‐TAPT hybrids via a similar synthetic strategy, [ 87 ] which exhibited significantly enhanced photocatalytic degradation efficiency toward Cr(VI), ponceau‐4R and Rh‐B.…”

Noble Metal-Free TiO2-Coated Carbon Nitride Layers for Enhanced Visible Light-Driven Photocatalysis

“…Photoluminescence (PL) spectra was shown in Figure 4c. The PL peak intensity is proportional to the recombination rates of the photogenerated electron-hole pairs [53]. g-C 3 N 4 has strong peak intensity, indicating that its charge separation efficiency is low.…”

Combining metal-organic frameworks (MOFs) and covalent-organic frameworks (COFs): Emerging opportunities for new materials and applications

“…On the contrary, COFs exhibited robust chemical stability beneficial for maintaining long-term stable performance [67,68], but the limited scope of covalent bonds used for construction of COFs has seriously obstructed their type diversity and multi-functionalization. Get two birds with one stone, novel porous materials via integrating both MOF and COF chemistries have inherited both advantages and even surpassed the performance of corresponding individuals in the application of adsorption [69,70], separation [71][72][73], catalysis [74][75][76][77][78][79] and so on [80][81][82][83][84][85].…”
