Abstract ：
A rational design of MNPs@MOFs (MNPs = metal nanoparticles, MOFs = metal-organic frameworks) nanocomposites is important for their application as multifunctional catalysts for light-initiated one-pot tandem/cascade reactions. Herein, the Pd@MIL-100(Fe) nanocomposite with a core-shell structure, in which Pd colloids of ca. 3 nm are encapsulated inside the matrix of MIL-100(Fe), was constructed successfully via self-assembly of MIL-100(Fe) in preformed PVP-capped Pd colloids (PVP = polyvinylpyrrolidone) at room temperature. Via a successful combination of MOF-based photocatalysis with Pd-based hydrogenation, Pdrpvp@MIL-100(Fe), with PVP partially removed, exhibited superior performance for the reaction between nitro aromatics and benzyl alcohols to produce secondary amines. Comparison of activity over Pdrpvp@MIL-100(Fe) with that of the other two types of MNPs/MIL-100(Fe) nanocomposites suggests that its superior activity can be attributed to the presence of well-stabilized stable Pd nanoparticles (NPs) for hydrogenation and the unoccupied cavities in MOFs to promote the mass diffusion, especially in the case of larger substrates, as well as an efficient charge transfer from the MOF to Pd NPs for their cooperation. This study indicates that a rational strategy in the construction of metal NPs/MOFs nanocomposites is important for their application as multifunctional catalysts for light-initiated one-pot tandem/cascade reactions.

Abstract ：
Heterojunctions combining two photocatalysts of staggered conduction and valence band energy levels can increase the photocatalytic efficiency compared to their individual components. This activity enhancement is due to the minimization of undesirable charge recombination by the occurrence of carrier migration through the heterojunction interface with separated electrons and holes on the reducing and oxidizing junction component, respectively. Metal-organic frameworks (MOFs) are currently among the most researched photocatalysts due to their tunable light absorption, facile charge separation, large surface area and porosity. The present review summarizes the current state-of-the-art in MOF-based heterojunctions, providing critical comments on the construction of these heterostructures. Besides including examples showing the better performance of MOF heterojunctions for three important photocatalytic processes, such as hydrogen evolution reaction, CO2 photoreduction and dye decolorization, the focus of this review is on describing synthetic procedures to form heterojunctions with MOFs and on discussing the experimental techniques that provide evidence for the operation of charge migration between the MOF and the other component. Special attention has been paid to the design of rational MOF heterojunctions with small particle size and controlled morphology for an appropriate interfacial contact. The final section summarizes the achievements of the field and provides our views on future developments. The present review summarizes the current state-of-the-art in MOF-based heterojunctions in three important photocatalytic processes: hydrogen evolution reaction, CO2 photoreduction and photodegradation of dyes.

Abstract ：
A 2D Mn-based MOF ([Mn4(PDI)2(DMF)7(H2O)]n (MOF 1)) (H4PDI = 5,5 '-(1,3,6,8-tetraoxo-1,3,6,8-tetrahydrobenzo[lmn][3,8]phenanthroline-2,7-diyl)diisophthalic acid) was synthesized. Visible light excited Mn-PDI unit in MOF 1 oxidizes NaSO2CF3 to generate center dot CF3 radical and enables MOF 1 to exhibit activity for trifluoromethylation of (hetero)arenes under visible light. The unusual stability of MOF 1 in the trifluoromethylation reactions can be attributed to its unique structure, which prevents it from corrosion by acid byproduct. The peeling of MOF 1 to ultrathin nanosheets or partial oxidation of Mn(II) to Mn(III) in MOF 1 led to MOL 1 and NB 1 with significant improved activity for trifluoromethylation reactions, demonstrating the important role of composition and morphology of a catalyst on its performance. The light initiated trifluoromethylation reactions over these Mn-based MOFs was applied to a variety of substrates. This study provides an efficient strategy for synthesis of trifluoromethylated compounds and highlights the potential of MOFs in light initiated organic syntheses.

Abstract ：
CdS/UiO-66-NH2 nanocomposite was solvothermally fabricated from cadmium acetate and the pre -synthesized UiO-66-NH2 in dimethyl sulfoxide (DMSO), which acted as the sulfur source. The as -obtained CdS/UiO-66-NH2 nanocomposite was immobilized on a glass fiber cloth (GF) and was applied for hydrogen sulfide (H2S) removal. The resultant GF immobilized CdS/UiO-66-NH2 nanocomposite exhibited a superior activity and high stability for H2S removal under visible light, in which UiO-66-NH2 acts as the main adsorbent and enriches H2S to promote CdS-based photocatalysis, while photocatalysis by CdS decomposes H2S adsorbed on UiO-66-NH2 to realize an in -situ regeneration of the adsorbent. The introduction of UiO-66-NH2 as the main adsorbent suppresses a fast deactivation of CdS due to an irreversible coordination between metal cation Cd2+ and H2S. This study not only developed a new type of material for fast and efficient removal of H2S, but also underscores the high potential of coupling physical adsorption and photocatalysis for the removal of volatile organic compounds (VOCs) and other gaseous pollutants in the environment.

Abstract ：
The valorization of native lignin to functionalized aromatic compounds under visible light is appealing yet challenging. In this communication, colloidal mercaptoalkanoic acid capped ultrathin ZnIn2S4 (ZIS) microbelts was successfully fabricated, which was used as a superior catalyst for depolymerization of native lignin in birch woodmeal under visible light, with an optimum yield of 28.8 wt % to functionalized aromatic monomers achieved in 8 h. The capped mercaptoalkanoic acid not only enables a solvent modulated reversible interchange of ZIS between the colloidal state for efficient reaction and the aggregated state for facile separation, but also serves as a precursor for light initiated generation of reactive thiyl radical for highly selective cleavage of β-O-4 bond in native lignin. This work provides a green and efficient strategy for the depolymerization of native lignin to functionalized aromatic monomers under mild conditions, which involves a new mechanism for the cleavage of β-O-4 bonds in native lignin. The capability of cleavage of β-O-4 bonds in native lignin by photogenerated thiyl radicals also demonstrates the great potential of using photogenerated thiyl radicals in organics transformations. © 2024 Wiley-VCH GmbH.

Abstract ：
The coupling between aryl halides and thiols to synthesize aryl thioethers via the formation of a C-S bond is an important reaction. In this manuscript, a Pd/ZnIn2S4 nanocomposite obtained via photoreduction of PdCl2(CH3CN)(2) in the presence of ZnIn2S4 was found to be an efficient bifunctional catalyst to realize the coupling reaction between thiophenols and aryl halides (X = Br and I) to yield aryl thioethers. A mechanism study reveals that the reaction involves the light-initiated generation of thiyl radicals as important intermediates. This reaction protocol can be applied to a wide range of substrate scopes, with moderate to excellent yields for the desired thioethers. This study provides a facile, green and economic strategy for the synthesis of aryl thioethers under mild conditions. This work also highlights the great potential of semiconductor-based photocatalysis in light-initiated organic syntheses.

Abstract ：
Carbon quantum dot (CQD)-decorated CdS nanocomposites were successfully fabricated via the self-assembly of CdS in the presence of preformed CQDs and were found to be efficient photocatalysts for the hydrogenation of nitrobenzene under visible light. Due to the presence of the frustrated Lewis acid-base pairs (FLPs) in their structure, CQDs act as an efficient catalyst to promote the proton-coupled hydrogenation of nitrobenzene over CQDs/CdS nanocomposites. Controllable and chemoselective hydrogenation of nitrobenzene to produce aniline, azoxybenzene, azobenzene and hydrazobenzene can be realized over CQDs/CdS via simply regulating the reaction medium including the hydrogen source, the solvent and the alkalinity. This study provides a highly efficient and economical photocatalytic system for the controllable and chemoselective hydrogenation of nitrobenzene under visible light. This work also highlights the great potential of semiconductor-based photocatalysis in light-initiated organic syntheses. Visible light-initiated chemoselective hydrogenation of nitrobenzene into different products is realized over CQDs/CdS via simply regulating the reaction medium.

Abstract ：
To resolve the pollution flashover problem of insulators, a novel application of nanosized TiO2 film to improve the ceramic insulator performance under contaminated conditions has been successfully developed. Compared with the uncoated insulator, TiO2 -coated insulator exhibits an enhanced self-cleaning performance induced by the photocatalysis and hydrophilicity of TiO2 film in the heavily contaminated surroundings. Moreover, the TiO2 -coated insulator also presents a better electric performance in power-frequency puncture voltage, power-frequency puncture voltage in dielectric oil, wet power-frequency flashover voltage, lightning impulse withstand voltage, and the artificial pollution flashover voltage due to the semi-conducting property of TiO2 film to make the distribution of the electric field more even. The synergy between these two effects helps to promote the performance of TiO2 -coated insulators for anti-pollution flashover. © 2023 WILEY-VCH GmbH.

Abstract ：
Photocatalysis, a promising technology to convert solar energy to chemical energy, is expected to relieve the global energy shortage and environmental pollution and therefore has attracted widespread recent research attention. Metal-organic frameworks (MOFs), a class of micro-mesoporous hybrid material constructed from metal or metal nodes interconnected with multi-dentated organic linkers, have recently been demonstrated to be promising photocatalysts for a variety of reactions relevant to environmental and energy concerns due to their unique structure and characteristics. Considering that MOF-based photocatalysis burgeoned rapidly during the past several years, and with an aim to develop more efficient MOF-based photocatalytic materials, it is still necessary to summarize the strategies already reported to improve the performance of MOF-based photocatalytic materials, even though several excellent reviews on MOF-based photocatalysis have already been published. In this review, four structural engineering strategies to improve the efficiency of MOF-based photocatalysis have been summarized. These strategies include metal doping, ligand functionalization, the fabrication of ultrathin 2D MOFs, and defect engineering. These methods aim to enhance light absorption, improve charge separation and transportation, and create more catalytic active sites. Personal opinions on the opportunities, challenges, and developing trends of MOF-based photocatalysis were addressed. This review aims to provide guidance for the rational development of advanced MOF-based photocatalysts by elucidating the inherent relationship between their structural properties and catalytic activity.
