Performance of supported metal catalysts in the dimethyl carbonate production by direct synthesis using CO2 and methanol

Novel Fe‐modified CeO2 Nanorod Catalyst for the Dimethyl Carbonate Formation from CO2 and Methanol

“…Besides, the intrinsic properties of iron oxides contribute to enhancing the acid-basic sites. [17] Moreover, incorporation of Fe into the CeO 2 sample increases the amount of Ce-OÀ Fe bonds on the surface, and also lead to the formation of FeÀ Ce oxygen vacancy and abundant acidbasic sites. [18] The Fe-modified CeO 2 nanorods possess a large amount of moderately acid-basic sites, and can act as an acidbasic bifunctional catalyst.…”

“…The iron oxide with acidic and basic properties, low cost and non-toxicity has been used as the active component or promoter of catalysts for DMC formation from methanol and CO 2 . [9] Li et al proposed to modify ZrO 2 with Fe and found that the addition of Fe could influence the crystal structure of the ZrO 2 , and increase the amount of the surface acidic and basic sites, contributing to activating the methanol and CO 2 . [10] The introduction of Fe into the Cu-based catalysts for the DMC formation was also reported.…”

Basicity as a Thermodynamic Descriptor of Carbanions Reactivity with Carbon Dioxide: Application to the Carboxylation of α,β-Unsaturated Ketones

“…Activation of CO 2 can be accomplished through reduction routes ( Francke et al, 2018 ; Melchionna et al, 2021 ) in which desirable products are carbon monoxide, formic acid, methanol, methane, or > C2 species ( Albero et al, 2020 ). Alternatively, carbon dioxide can be exploited in cyclic carbonates or heterocycle formation ( North et al, 2010 ; Fiorani et al, 2015 ; Yu and He, 2015 ; Guo et al, 2021 ; Vieira et al, 2018 , 2019 ; Faria et al, 2021 ) or as a single-carbon-atom building block for its fixation into organic compounds ( Liu et al, 2015 ; Cao et al, 2018 ; Cherubini-Celli et al, 2018 ; Tlili and Lakhdar, 2020 ; Zhang et al, 2020 ; Sahoo et al, 2021 ; Yuan et al, 2021 ; He et al, 2020 ) upon creation of new C-C or C-heteroatom bonds. Mechanistically, these processes can be accomplished through 1) the reduction of carbon dioxide to its radical anion, followed by its reaction with the organic scaffold (in dimethylformamide, E 0 (CO 2 /CO 2 •– ) = −2.21 V vs. saturated calomel electrode, SCE, corresponding to −1.97 V vs. standard hydrogen electrode) ( Lamy et al, 1977 ; Otero et al, 2006 ; Berto et al, 2015 ) or 2) upon the formation of reduced intermediates of the organic substrate accomplished through chemical, electrochemical, or photochemical routes and their subsequent reactivity with CO 2 ( Yuan et al, 2021 ).…”

Extensively amino-functionalized graphene captures carbon dioxide

“…The latter greatly benefits from the explosive development of novel fascinating catalysis schemes. 18,27,37,38,42,[44][45][46] Non-aqueous solvents, such as pure and functionalized ionic liquids, have been thought to form a basis for alternative green solutions for CO 2 capture. More recent options include deep eutectic solvents (DESs) for the same purpose.…”
