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 ：
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 ：
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 ：
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 ：
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 ：
2D Ni-Fe-MOF ultrathin nanosheets (NSs), with dimensions of ca. 1.0 mu m and thickness of ca. 5.0 nm, were successfully fabricated. Small-sized Pd nanoparticles of ca. 3.0 nm were deposited on 2D Ni-Fe-MOF NSs to afford Pd/Ni-Fe-MOF NSs, which were used as an efficient multifunctional catalyst to realize the N-alkylation reactions of amines by alcohols under visible light. The superior performance observed over the resultant Pd/Ni-Fe-MOF NSs as compared with Pd/bulk Ni-Fe-MOF, their 3D counterpart, can be ascribed to the ultrathin nanosheet morphology of 2D Ni-Fe-MOF NSs, which not only shortens the transportation path for the photogenerated charge carriers, but also can provide more efficient interaction between the active site and substrates. This work provides a green and sustainable strategy for the production of secondary amines using alcohols as the alkylating agent. This study also demonstrates the unique advantages of 2D MOF ultrathin nanosheets in the fabrication of multifunctional catalytic systems for light initiated one-pot tandem/cascade reactions.

Abstract ：
PtS/ZnIn2S4 nanocomposites are obtained via a microwave-assisted synthesis followed by a photoreduction. The resultant PtS/ZnIn2S4 nanocomposites are used as an effective multifunctional photocatalyst for the reaction between alcohols and o-aminobenzamide to coproduce quinazolinones and hydrogen under visible light, via a cascade alcohols/aldehydes transformation, condensation between aldehydes and o-aminobenzamide, as well as the dehydrogenation/cyclization to produce quinazolinones. PtS acts as an efficient cocatalyst to promote the dehydrogenation of both the alcohols and the condensation intermediates for the production of quinazolinones. An almost complete conversion of o-aminobenzamide was achieved in 24 h, with a yield of 98.8% to 2-phenyl-quinazline-4(3H)-one and quantitative hydrogen produced over PtS/ZnIn2S4 after irradiated for 24 h. The apparent quantum yield at 450 nm is determined to 15.2%. The superior activity observed over PtS/ZnIn2S4 nanocomposite as compared with that over either NiS/ZnIn2S4 or MoS2/ZnIn2S4 can be ascribed to a moderate binding between PtS and the surface adsorbed H*. This study supplies an effective, green, and atom-economic strategy for the synthesis of quinazolinones with coproduction of hydrogen under visible light. This work also demonstrates the high potential of fabrication of metal sulfide-based multifunctional catalysts for light-driven one-pot tandem/cascade reactions.

Abstract ：
Ternary NiTiFe-LDH with an ultrathin nanosheet morphology was successfully fabricated via a facile co-precipitation method, followed by refluxing, and was used as a catalyst for oxidative coupling of amines to produce imines under visible light. The obvious superior activity observed in NiTiFe-LDH ultrathin nanosheets compared with binary NiTi-LDH and bulk NiTiFe-LDH can be ascribed to an enhanced light absorption capability caused by the introduction of Fe3+ ions as well as the ultrathin nanosheets which can minimize the recombination of the photogenerated charge carriers and provide more catalytically active sites for the reaction. As a result, more catalytically active O2- radicals are generated over NiTiFe-LDH ultrathin nanosheets, which leads to their superior activity. This study not only shows the possibility of using LDHs in photocatalytic organic transformations but also demonstrates an effective strategy to promote the activity of LDH-based photocatalysts via simultaneous composition and morphology modulation of LDHs. Due to the introduced Fe3+ for enhanced light absorption and the ultrathin nanosheets to minimize the recombination of photogenerated charge carriers, NiTiFe-LDH NSs exhibit superior activity for conversion of amines to imines under visible light.
