Recent progress in CO₂ conversion into organic chemicals by molecular catalysis

Abstract

Chemical conversion of carbon dioxide (CO2) into high-value chemicals or fuels is exceedingly attractive due to its green and sustainable features. However, practical technologies on scale utilisation of CO2 is...

A two-electron reducing reaction of CO2 to an oxalate anion: a theoretical study of delocalized (presolvated) electrons in Al(CH3)n(NH3)m, n = 0–2 and m = 1–6, clusters

“…A very large number of publications in 2023 testify to the high level of activity of researchers in this field. 57–62…”

Controlling dual-positively charged pyrazolium ionic liquids for efficient catalytic conversion of CO2 into carbonates under mild conditions

“…This has intensified the greenhouse effect, causing global warming and environmental damage. Two main strategies have been used to address this issue thus far: carbon dioxide capture and storage 1 and the conversion of CO 2 into beneficial chemical compounds. 2–4 Both tactics view CO 2 as a non-toxic, natural, renewable, abundant, nonflammable resource and low-cost C1 building block.…”

Salophen-type Organocatalysts for the Cycloaddition of CO2 and Epoxides under Solvent, Halide, and Metal-Free Conditions

“…Currently, a challenge in the development of methodologies based on sustainable processes for obtaining chemical products is the effective use of renewable resources. Carbon dioxide (CO 2 ) is a renewable feedstock since it is a waste product of different industrial activities and is therefore cheap and available. , Currently, the chemical industry uses less than 1% of total CO 2 emissions as a feedstock, mainly for synthesizing urea, salicylic acid, polycarbonates, polyurethanes, and cyclic carbonates. , Due to its high stability and low reactivity, CO 2 requires a well-designed activation and thermodynamic driving force for efficient transformations. − Hence, advances have been made for the activation/use of CO 2 , i.e., activation in transition-metal-mediated reactions or by reacting CO 2 with compounds such as amines, epoxides, and molecular hydrogen. − From the green chemistry and sustainability approach, obtaining cyclic carbonates is relevant since they present potential applications, besides being the thermodynamically favored product of this reaction. , Cyclic carbonates have a wide use field, such as electrolytic solvents for lithium-ion batteries and environmentally friendly polar aprotic solvents and moreover providing an alternative to the use of phosgene, acting as monomers to produce polycarbonates. , …”
