Functional porous poly(ionic liquid)s catalyst for highly integrated capture and conversion of flue gas CO2

A Three-Dimensional Azo-Bridged Porous Porphyrin Framework Supported Silver Nanoparticles as the State-of-the-Art Catalyst for the Carboxylative Cyclization of Propargylic Alcohols with CO2 under Ambient Conditions

“…Hence, 2-methyl-3-butyn-2-ol is used as a representative substrate to evaluate the catalytic performance of Ag/Azo-Por-TAPM . According to the reported works, ,,, 1,8-diazabicyclo[5.4.0]­undec-7-ene (DBU) usually serves as an efficient alkaline additive to activate the hydroxyl group of the propargylic alcohol. The reaction conditions of room temperature (25 °C) and atmospheric pressure (1 bar) are selected to highlight the catalytic efficiency of the catalyst because of its enhanced CO 2 adsorption performance.…”

Dialkyl Carbonate Synthesis Using Atmospheric Pressure of CO2

“…In addition, monoalkyl carbonates [ROC­(O)­O] − are often found as reaction intermediates in DRC synthesis; therefore, it is possible to construct reaction systems in which [BASE-H]­[ROC­(O)­O] is directly involved in catalysis, depending on the catalyst used. Some research has been reported on application of CO 2 chemisorption such as the [BASE-H]­[ROC­(O)­O] formation for synthesis of useful organic compounds. − In previous studies for diethyl carbonate (DEC) synthesis, Wu et al. and Kim et al independently reported DRC synthesis in the presence of organic bases, but they do not address the formation of [BASE-H]­[ROC­(O)­O] and its impact on the reaction outcome, nor did they investigated DRC synthesis under low-pressure and low-concentration CO 2 . , By contrast, Liu et al and Nozaki et al accomplished DRC synthesis under low-pressure CO 2 via [BASE-H]­[ROC­(O)­O]; CH 2 Br 2 and alkyl triflates were used as halogenated alkylating agents. , Herein, we report a cooperative combination of DBU for the chemical capture of CO 2 , tetraalkyl orthosilicate (Si­(OR) 4 , TROS) as the dehydrating agent, and CeO 2 as the catalyst for the synthesis of DRC using atmospheric pressure CO 2 (Scheme ).…”

Porous Polymers Based on 9,10-Bis(methacryloyloxymethyl)anthracene—Towards Synthesis and Characterization

“…A variety of contemporary achievements relies on porous components. These materials are successfully utilized as column packing in different chromatography techniques [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ], as filtration/separation membranes [ 10 , 11 ], as support for sensors and catalysts [ 12 , 13 , 14 ], as transporters in drug delivery systems [ 15 , 16 , 17 ]. They are also widely applied for detection and removal of pollutants from water [ 18 , 19 ], for CO 2 capture [ 20 , 21 ], separation of rare earth elements [ 22 ] and many others advanced applications [ 23 , 24 , 25 , 26 , 27 , 28 , 29 ].…”
