Well dispersed gold nanoparticles into the multi amine functionalized SBA-15 for green chemical fixation of carbon dioxide to cyclic carbonates under solvent free conditions

Recent developments in state-of-the-art silica-modified catalysts for the fixation of CO2 in epoxides to form organic carbonates

“…Also, the reduction in the yield after several recycles of the catalyst was due to the poisoning of the catalyst with the reactants or products and also leaching of the gold nanoparticles. 178…”

Synthesis of TBAB‐based Deep Eutectic Solvents as the Catalyst in the Coupling Reaction between CO2 and Epoxides under Ambient Temperature

“…Thus, determining how to capture and convert CO 2 into high‐value chemicals has become a hot topic [2–6] . Recently, CO 2 as a non‐toxic, cheap, and abundant C1 resource has been transformed into high‐value products such as methanol, formic acid, cyclic carbonates, etc [7–12] . Among these products, cyclic carbonates, which have broad applications as polar solvents, electrolytes, and fine chemicals in organic syntheses, can be prepared from the coupling reaction between CO 2 and epoxides, via a green and 100 % atom economy reaction [13–17] .…”

“…[2][3][4][5][6] Recently, CO 2 as a non-toxic, cheap, and abundant C1 resource has been transformed into high-value products such as methanol, formic acid, cyclic carbonates, etc. [7][8][9][10][11][12] Among these products, cyclic carbonates, which have broad applications as polar solvents, electrolytes, and fine chemicals in organic syntheses, can be prepared from the coupling reaction between CO 2 and epoxides, via a green and 100 % atom economy reaction. [13][14][15][16][17] Hence, converting CO 2 to high-value-added cyclic carbonates can not only reduce the CO 2 concentration, but also obtain valuable organic compounds from the non-toxic C1 resource.…”

Lead-Decorated Titanium Oxide Compound with a High Performance in Catalytic CO2 Insertion to Epoxides

“…While CO 2 is widely acknowledged as the major greenhouse gas responsible for global warming, it can also be viewed as a widely and globally available, affordable, and harmless carbon source in the toolkit of synthetic chemists. − As a result, CO 2 catalytic conversions have attracted a lot of attention, − particularly the synthesis of five- and six-membered cyclic carbonates from CO 2 and epoxides, − by which the afforded cyclic carbonates are very useful polar aprotic solvents and important components of the electrolyte in lithium-ion batteries. Toward this transformation, recently, a great amount of effort has been made on various catalyst materials containing Lewis acidic or basic sites, such as metal–organic frameworks (MOFs), , covalent–organic frameworks (COFs), , and heterogeneous gold, silver, and platinum catalysts. ,− Although these systems show very high efficiency, they are usually performed in relatively harsh conditions, such as high temperature and high pressure . In contrast, photocatalysis uses sunlight as the energy source and triggers chemical reactions under very mild conditions.…”
