| 1 | Recent advances in metal-organic frameworks for catalytic CO_(2) hydrogenation to diverse products显示文摘Selective hydrogenation of CO_(2) to high value-added chemicals,not only gives an effective way to reduce the concentration of CO_(2),but also provides the precursors to advance the industrial manufacturing of chemicals and fuels.With the well-defined reticular frameworks and flexible modifiability,metal-organic frameworks(MOFs)can be the ideal platform to construct the enabled catalysts for CO_(2) hydrogenation,because they have shown the great potential for the enhancement of catalytic activity,the precise control of selectivity,and the excellent stability.In this review,we systematically summarize the recent advances in MOFs based catalysts for CO_(2) hydrogenation towards diverse products.Firstly,synthesis strategies for different kinds of MOFs based catalysts are described.Secondly,selective hydrogenation of CO_(2) towards CO and methane is discussed over various metal nanoparticles/MOFs composites.Thirdly,heterogenization and isolation of molecular catalysts by MOFs are elaborated for producing formic acid.Fourthly,selective hydrogenation of CO_(2) toward methanol is discussed in terms of interface structures of Cu,Zn,and metal nodes of MOFs,the synergy between auxiliary sites and noble metal,and tandem catalytic systems of molecular catalysts and Lewis acid sites.Subsequently,the integration of multiple metal sites,promoters,and cocatalysts into MOFs is described for the selective hydrogenation of CO_(2) to C2+products.After those,the key issue about the stability of MOFs based catalysts for CO_(2) hydrogenation reaction is discussed.Finally,the summary and perspective about MOFs based catalysts for selective CO_(2) hydrogenation and mechanism research are proposed. | Shengxian Shao Chengqian Cui Zhiyong Tang Guodong Li | 2022 | Nano Research2022，15，12： | 2 |
| 2 | Recent Advances on Confining Noble Metal Nanoparticles Inside Metal-Organic Frameworks for Hydrogenation Reactions显示文摘Hydrogenation reaction is one of the pillars of the chemical industry for the synthesis of drugs and fine chemicals.To achieve high catalytic performance,it is still highly desirable for constructing novel supported metal catalysts.Different from conventional supports like metal oxides,zeolites and carbon materials,metal-organic frameworks(MOFs)as the emerging porous materials have exhibited great potential to host metal nanoparticles(NPs)for achieving hydrogenation reactions with high catalytic efficiency,due to their unique porous structures.Recently,many progresses have been made,and thus,it is necessary to summarize the recent progresses on confining metal NPs inside MOFs for hydrogenation reactions.In this review,we first introduced the general synthesis methods for confining noble metal NPs inside MOFs.Then,the applications of noble metal NPs/MOFs catalysts in hydrogenation reactions were summarized,and the synergistic catalytic performances among noble metal NPs,metal nodes,functional groups,and pore channels in MOFs were illustrated.Subsequently,the hydrogen spillover effect involved in the hydrogenation reactions was discussed.Finally,we provide an outlook on the future research directions and challenges of confining noble metal NPs inside MOFs for hydrogenation reactions. | LIN Tian WANG Haowu CUI Chengqian LIU Wei LI Guodong | 2022 | Chemical Research in Chinese Universities2022，38，6： | 1 |
| 3 | Coordinating Zirconium Nodes in Metal-Organic Framework with Trifluoroacetic Acid for Enhanced Lewis Acid Catalysis显示文摘Regulating Lewis acid sites with well-defined electronic state and steric environment is still challenging for achieving high catalytic efficiency.Here we show coordinating zirconium nodes in the typical metal-organic framework known as MOF-545 with the monocarboxylate modulators including trifluoroacetic acid(TFA)or benzoic acid(BA)over meso-tetra(4-carboxyphenyl)-porphine(H_(2)TCPP),denoted as MOF-545-TFA or MOF-545-BA.Impressively,MOF-545-TFA shows the significantly enhanced performance for the catalytic ring-opening reaction of various epoxides with alcohols and good recyclability at 40°C in respect with MOF-545-BA and ZrO_(2).This mainly originates from the stronger Lewis acidity and more active zirconium sites induced by the electron-withdrawing TFA,resulting in the increased ability for activation of epoxides.This modulation approach is promising for enlarging the toolbox to extend the MOFs-based Lewis acid catalysis. | WANG Wenyang LIU Hanlin YANG Caoyu FAN Ting CUI Chengqian LU Xiaoquan TANG Zhiyong LI Guodong | 2022 | Chemical Research in Chinese Universities2022，38，5： | 0 |
| 4 | Metal-organic framework nanosheets and their composites for heterogeneous thermal catalysis:Recent progresses and challenges显示文摘Metal-organic framework nanosheets(MONs)as the emerging materials have been attracting great interest because the nanosheets possess a range of fascinating attributes including high surface areas and sufficient accessible active sites,and their nanoscale thicknesses are favorable for mass diffusion and transfer of substrates and products with respect to bulk metal-organic frameworks(MOFs).This review first summarizes the synthetic methods of various MONs from top-down and bottom-up methods as well as their diverse composites with different components.Then,the catalytic applications of MON based nanocatalysts are discussed and the relationships among the composition,structure and catalytic performances are revealed.Finally,the challenges and future outlook about the synthesis of diverse MONs and their composites for heterogeneous catalysis are prospected. | Chengqian Cui Guodong Li Zhiyong Tang | 2021 | Chinese Chemical Letters2021，32，11： | 0 |
