Squaramide-derived framework modified periodic mesoporous organosilica: A robust bifunctional platform for CO2 adsorption and cooperative conversion

Applications of porous frameworks in solid‐phase microextraction

“…Prepared PMOs showed both amorphous and crystalline pore walls [98]. Due to multi‐functionality, capability of modification, high surface area, biodegradable, and high stability, they were employed in different efforts such as sensors [99], drug delivery [100], and gas adsorption [101]. Structures of some PSFs such as EMM‐37 as zeolite [102], SBA‐15 [103], and PMO‐THEIC [104] were shown in Table 2.…”

Azo‐Functionalized Zirconium‐Based Metal−Organic Polyhedron as an Efficient Catalyst for CO2 Fixation with Epoxides

“…The catalytic performance of Zr-AZDA is comparable to that of the best homogeneous catalyst (such as NaI • 2H 2 O and Co-Salen), [15,18] and Zr-AZDA also shows higher catalytic activity than most of the reported heterogeneous catalysts (such as Basic-Nano-ZSM-5-Pr-MIM-OH, PIPÀ Bn-Cl, PS-ImHI, MgÀ Al mixed Oxide, MgO nanoparticle, IT-POP-1, CNTammonium salt, MOPÀ Zn-1, CuTrp MOF, Helicate cage, Nu-1000 and Hf-NU-1000). [24,25,[27][28][29]31,36,44,55,64,65] Although the catalytic reaction conditions used in the literatures are versatile, in general the Zr-AZDA catalyst has obvious advantages such as mild reaction conditions, solvent-free at atmospheric pressure (1 atm) and higher catalytic activity.…”

“…To facilitate the process, a number of catalysts have been developed. So far, both homogenous catalysts (such as halogen bond donor catalysts, [9] phosphonium salts, [10,11] ionic liquids, [12][13][14] alkali metal halides [15,16] and metal-salen complexes [17][18][19][20][21][22] ), and heterogeneous catalysts (such as functional zeolite, [23] organosilica, [24] porous ionic polymers, [25] ionic liquid-supported solids, [26,27] metal oxides, [28][29][30] polymers, [31] organic network, [32,33] porous carbons, [34][35][36] bifunctional catalysts [37,38] and metalÀ organic frameworks (MOFs)) have been available for the CO 2 fixation into cyclic carbonates. [39,40] Among these, technically recoverable heterogeneous catalysts such as MOFs have attracted much attention due to their characteristics of high surface area, uniform pore structure and tunable functionalities.…”

Enhancement in the active site exposure in a porphyrin-based PIL/graphene composite catalyst for the highly efficient conversion of CO2

“…There are many reports on the synthesis of cyclic carbonates (COCs) from CO 2 and epoxides. [7][8][9][10][11][12][13][14] These reactions have a high atomic economy, and COCs are valuable chemicals, which have been widely used as polar aprotic solvents, battery electrolyte components, plasticizers, and organic synthesis intermediates. 15 CO 2 has high thermodynamic and kinetic stability, so that the activation of CO 2 is forced to require higher temperature and harsher reaction conditions.…”
