Postsynthetic ionization of an imidazole-containing metal–organic framework for the cycloaddition of carbon dioxide and epoxides

Abstract

A bifunctional imidazolium functionalized Zr-based metal–organic framework, (I–)Meim-UiO-66, was successfully prepared, which can serve as an efficient heterogeneous catalyst towards the capture and coupling of CO2 with epoxides.

Porous Metal‐Organic Polyhedral Framework containing Cuboctahedron Cages as SBUs with High Affinity for H2 and CO2 Sorption: A Heterogeneous Catalyst for Chemical Fixation of CO2

“…The incorporation of secondary building units (SBUs) such as the well-known M 2 (carboxylate) 4 paddlewheel moiety was shown to produce av ariety of MOFs. [37][38][39][40][41][42][43][44][45][46][47] This approach will help in diminishing the concernedg reenhouse gas,a sw ell as generation of valuable chemicalc ommodities. [11][12][13][14][15] However with the increasing size of the cavi-ties or pores increases the probability of interpenetration of the frameworks, which reduces the cavity size but increases the stability.…”

“…[9,10] Moreovert he expansion of the pore size and surfacea rea of MOFs can be strategically achieved by enlarging the ligand, or by aggregating severalS BUs into biggerc lusters:s upramolecular building blocks (SBBs). [37][38][39][40][41][42][43][44][45][46][47] However,t he design and synthesis of more efficient and robustM OFs is very much necessary for the effective fixation of CO 2 with high yields and high turnover frequencies. [16][17][18][19][20] Several porous frameworks containing nitrogen-rich functional groups,s uch as pyridine, amine, imidazole and acylamide, were shown to have ag reater affinity towards the storing of carbon dioxide (CO 2 ).…”

“…[21][22][23][24][25] Development of porous materials that can efficiently adsorb and store H 2 and CO 2 is in demandg iven their practical utility.T he problemsw ith the use of carbon-based fuel can be solved by employing H 2 gas as a dense fuel, as it does not produce any kindo fc arbon emission. [37][38][39][40][41][42][43][44][45][46][47] This approach will help in diminishing the concernedg reenhouse gas,a sw ell as generation of valuable chemicalc ommodities. CO 2 is one of the primary anthropogenic gases, and foremost culprit for global warming and subsequentc limate change.…”

Tin(IV) Sulfide Greatly Improves the Catalytic Performance of UiO‐66 for Carbon Dioxide Cycloaddition

“…[5] Up to now,alot of catalysts have been used in cycloadditionr eactions of CO 2 ,s uch as metal-salen complexes, [6] ionic liquids, [7] lanthanide oxychloride, [8] functional polymers, [9] andm etal-organic frameworks (MOFs). [11][12][13][14][15][16][17] However,t he catalytic activities of MOFs are largely restricted mainly because of blockage of the active metal centers by organic linkers.
