ZIF‐8‐Nanocrystalline Zirconosilicate Integrated Porous Material for the Activation and Utilization of CO₂ in Insertion Reactions

Abstract

The conversion of CO2 to useful chemicals, especially to atom economical products, is the best approach to utilize an excess of CO2 present in the atmosphere. In this study, a metal‐organic framework (ZIF‐8) is integrated with nanocrystalline zirconosilicate zeolite to develop an integrated porous catalyst for CO2 insertion reactions. The catalyst exhibits excellent activity for the CO2 insertion reaction of epoxide to produce cyclic carbonate in neat condition without the addition of any co‐catalyst. The catalyst is stable and recyclable during the cyclic carbonate synthesis. Further, the catalyst also exhibits very good activity in another CO2 insertion reaction to produce quinazoline‐2,4(1H, 3H)‐dione.

Cu–Ce Bimetallic Metal–Organic Framework-Derived, Oxygen Vacancy-Boosted Visible Light-Active Cu2O–CeO2/C Heterojunction: An Efficient Photocatalyst for the Sonogashira Coupling Reaction

“…The unique physicochemical properties of MOFs and MOF-derived metal/metal oxide nanocomposites have been widely explored in photocatalysis. − MOFs can also act as a template for synthesizing metal/metal oxide decorated nanoporous carbon with tunable structural properties . Several MOFs and MOF-derived metal/metal oxide nanocomposites have been reported for unique catalytic applications. − Kar et al synthesized Cu–Cu 2 O/C and CuO-Cu 2 O/C by systematically carbonizing the Cu-BTC MOF and demonstrated the C–C, C–N cross-coupling reaction under conventional thermal catalytic conditions . Herein, the aim is to develop a sustainable photocatalyst having a good light absorption ability and reactivity for the C–C Sonogashira cross-coupling reaction.…”

Imidazole‐Based Energetic Materials: A Promising Family of N‐Heterocyclic Framework

“…In recent years, along with growing concerns about multidisciplinary integration, imidazoles have shown considerable potential in materials science [18–19] . Zeolitic imidazolate frameworks (ZIFs) material is formed by the self‐assembly of imidazole and transition metal Zn(II) or Co(II) coordination, which not only combines the structural advantages of natural zeolite and metal framework materials but also overcomes the shortcomings of poor thermal stability and chemical stability of traditional metal‐organic framework materials to a certain extent [20–21] . ZIF‐8, as a classic ZIFs material, is obtained by the coordination assembly of Zn(II) and 2‐methylimidazole [22] .…”

[22] With its excellent physical and chemical properties and flexible modifiability, continued exploration has been carried out in catalysis, separation and adsorption, electrochemistry, biomedicine, and sensors.…”

A Reusable Efficient Green Catalyst of 2D Cu-MOF for the Click and Knoevenagel Reaction

“…Zeolite imidazolate frameworks (ZIFs) [ 21 , 22 , 23 ] have arisen as a novel type of highly porous materials along with the advantages in the field of conventional MOF catalyst. By using ZIFs as solid acid catalysts, several organic transformation reactions have been carried out, such as Knoevenagel condensation [ 24 , 25 ], aldol condensation [ 26 , 27 ], Suzuki cross-coupling [ 28 , 29 ], Friedel–Crafts alkylation [ 30 , 31 ], and epoxide ring-opening reaction [ 32 , 33 ]. Current research in this area has been mostly focused to develop low-cost reusable recycling green catalysts to support sustainable development.…”
