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.

Nitrogen-rich metal organic frameworks (MOFs) structures have a great potential for the chemical fixation of CO2. In this direction, we utilized highly efficient nitrogen-rich dual linker MOF nickel(ii) as heterogeneous catalyst in solvent-free CO2 into cyclic carbonates at ambient pressure. present work, nickel-MOF, Ni-ImzAdn, was synthesized from imidazole and adenine linkers under hydrothermal conditions (Imz = Imidazole Adn Adenine). The Ni-ImzAdn characterized thoroughly via various physicochemical analyses such FT-IR, SEM, EDX, EDX-mapping, XRD, ICP-OES, BET, BJH, TG-DTA, CO2-TPD, NH3-TPD. with adequate free nitrogen sites exhibit high catalytic activity cycloaddition styrene oxide (93% yield) attributed to synergistic effect strong Lewis acid base on catalyst, which were acquired by NH3-TPD respectively. addition, presented recyclable without significant loss after six reaction cycles low ion leaching (analyzed (ICP-OES)). Thermogravimetry-differential thermal analysis (TG-DTA) showed had stability up 318 °C.

Dicationic ionic liquid‐grafted UiO‐66 as efficient catalyst for CO₂ conversion into cyclocarbonate under cocatalyst‐free and solventless conditions

Applied Organometallic Chemistry, Год журнала: 2024, Номер 38(11)

Опубликована: Июль 16, 2024

CO 2 chemical fixation offers a feasible approach for carbon mitigation and high‐value utilization, but it is still challenging to develop an efficient catalyst conversion into cyclic carbonate. Herein, the triethylenediamine‐derived dicationic ionic liquids (DIL‐X, X = Cl, Br, I) were grafted UiO‐66 linkers through self‐assembly of Zr 4+ ions mixed ligands terephthalic acid DIL‐bearing dicarboxylic acid, resulting in UiO‐66‐DIL‐X n , ( designated as molar amount feeding DIL‐X). Their catalytic performance was evaluated by epoxide cycloaddition reaction absence solvent cocatalyst. Among them, UiO‐66‐DIL‐Cl 0.4 exhibited outstanding performance, with chloropropene carbonate yield 92% high selectivity 99% under 0.1 MPa at 110 °C 16 h. Its activity could be ascribed cooperativity among Lewis acidity MOF nodes, enhanced absorption, strong nucleophilicity offered halogen liquid‐modified MOF. Moreover, presented excellent recyclability substrate extension. A potential mechanism epoxide‐CO has been proposed. This work will shed light on rational design functionalized MOFs‐based catalysts CO₂ utilization.
