Tuning functional ionic deep eutectic solvents as green sorbents and catalysts for highly efficient capture and transformation of CO2 to quinazoline-2,4(1H,3H)-dione and its derivatives

Electrocatalysis in deep eutectic solvents: from fundamental properties to applications

“…The presence of versatile interactions in DESs significantly increases the solubility for small molecules, which is favorable for the adsorption and conversion of small molecules in electrocatalytic reactions. 62–65 Besides, interactions in DESs could construct supramolecular networks to control the growth direction of materials and could also play significant roles in activating reactants and stabilizing intermediates, 30,40,66–68 making DESs promising candidates as electrolytes for electrocatalysis.…”

Deep eutectic solvents as a versatile platform toward CO2 capture and utilization

“…Several DESs have been found to be efficient for cycloaddition of CO 2 and epoxides, which is the most commonly reported CO 2 conversion under DES catalysis. Additionally, carbamate 134 and quinazoline-2,4(1 H ,3 H )-dione 135 have also been in situ synthesized from CO 2 in DESs. Accordingly, this section will concentrate on the cycloaddition reaction and corresponding well-designed DESs.…”

CO2 capture by imidazolium-based deep eutectic solvents: the effect of steric hindrance of N-heterocyclic carbenes

“…The DESs containing amino groups can chemically capture CO 2 by forming carbamate species. [20][21][22][23][24] Anion-functionalized DESs exhibit promising chemisorption performances for CO 2 , [25][26][27][28] such as azolide-based DESs 29,30 and phenolate-based DESs. 31,32 The CO 2 capture mechanisms of anion-functionalized DESs present various reaction pathways depending on the structures of the components of the DESs.…”

“…The new peak at 1638 cm À1 is attributed to the -COO À asymmetrical stretching of EG-based carbonate, and the peak appearing at 1285 cm À1 is the O-COO À stretching band. 25,27,29,36 The…”
