Abstract The conversion of CO 2 into value-added chemicals and fuels is one the potential approaches to deal with environmental issues caused by increasing carbon dioxide concentration in atmosphere. can be transformed a variety valuable products, including but not limited monoxide, cyclic carbonates, formic acid, methanol, methane, ethanol, acetic propanol, light olefins, aromatics, gasoline through thermal catalysis, electrocatalysis, photo(electro)catalysis. In ongoing search for new catalytic conversions, utilization carbon-based materials as catalyst supports demonstrates improvement performance. This because unique features carbonaceous supports, such tunable porous structure, high specific surface area, good chemical stability, excellent conductivity. Though there are other strategies chemicals, cycloaddition, methanation, hydrogenation, photocatalysis, five-membered carbonates has garnered significant attention its address concerns reduce reliance on fossil fuels; however, it faces considerable challenges due thermodynamic stability . To these issues, this review particularly presents recent advancements fixation carbonate using carbonaceous-supported systems viz. graphitic nitride, graphene, nanotubes, nanofiber, activated carbon, sphere, that provide advantages structures, areas, stability. Furthermore, easily modified introducing defects or heteroatoms enhance their provides information current research, development trends, necessary path expedite technological technologies terms materials, various experimental conditions employed reactions. important role molecular process modeling implementing at commercial scale also highlighted. aims demonstrate catalysts improve efficiency production, thereby contributing more sustainable processes.

Abstract A new nickel catalyzed cross‐electrophile coupling for accessing γ‐lactams (isoindolinones) as well γ‐lactones (isobenzofuranones) via carbonylation with CO 2 is documented. The protocol exploits the synergistic role of redox‐active Ni(II) complexes and AlCl 3 a activator/oxygen scavenger, leading to formation wide range cyclic amides esters (28 examples) in good high yields (up 87 %). dedicated computational investigation revealed multiple roles played by . In particular, simultaneous transient protection pendant amino group starting reagents electrophilically activated ‐AlCl adduct are shown concur paving way an energetically favorable mechanistic pathway.

Climate change is a serious global problem. CO2 of paramount importance in mitigating this environmental Understanding the interaction with functionalized carbon structures essential for designing new materials to aid efficiently capturing CO2. In work, between dioxide (CO2) and coronene models, simulating graphene asphaltene moiety, was studied through DFT (CAM-B3LYP-D3) DLPNO-CCSD(T) methods investigate effect nitrogen doping two arrangements. Aromaticity, electronic, topological properties were evaluated using HOMA, HOMO-LUMO gap, QTAIM, NCI methods. The results show that adsorption molecule dependent on position heteroatom governed by noncovalent interactions, such as van der Waals hydrogen bonds. CO2/N-coronene complex pyridinic-N stabilized due unconventional bonds parallel aromatic π system. We hope present can help synthesis inhibitors precipitation better systems capture.
