“…As presented in Figure 2 and 3A, the peak at 2337 cm –1 represented the asymmetric stretching of the physisorbed CO 2 , while the peak at 1718 cm –1 denoted the formation of DOP-N-CO 2 – Na + , which verified the results obtained by 13 C NMR spectroscopy and in a good agreement with the results recorded previously for EPN. 44 Moreover, the ATR-FTIR spectra of TYR fortified the chemisorption of CO 2 through the emergence of a new peak at 1701 cm –1 (Figure 3B).…”

“…Under air conditions, the color change associated with EPN·HCl upon activation with a metal hydroxide 44 is an indicator of oxidation as a result of hydroquinone/quinone conversion, 45 which motivates exploring the stability of related biomaterial architectures. The photographs of EPN·HCl, DOP·HCl, TYR·HCl, and PEA·HCl dissolved in DMSO before and after activation with a NaOH pellet are shown in Figure 1.…”

“…Although the hydroxyl groups are also potential reaction sites, previous DFT calculations with EPN showed that the amine groups are more reactive. 44 Figure 6 shows the optimized structure of the sequestrated products, and the carbamate (−NCOO – ) adduct is stabilized by ion–ion interaction with Na + , as indicated by the short interaction distances (Figure 6). In the case of EPN, the structure of the formed adduct is stabilized by an additional intramolecular hydrogen bond (ca.…”

“…Very recently, our group has reported on the chemisorption of CO 2 by biomaterials, viz., epinephrine, 44 (EPN, a catecholamine neurotransmitter, Scheme 2) when dissolved in DMSO through the formation of alkali metal carbamate (RR′NCO 2 – X + ) upon activation of its acidic form with a metal hydroxide. According to National Institutes of Health, biomaterials are defined as any matter, surface, or construct that interacts with biological systems that can be derived from nature or synthesized in the laboratory using metallic components, polymers, ceramics, or composite materials.…”

A new series of 2-aminoethyl-benzene-based biomaterials, namely, dopamine (DOP), tyramine (TYR), phenylethylamine (PEA), and epinephrine (EPN), dissolved in dimethylsulfoxide (DMSO) have been investigated for CO 2 capture upon activatiing their hydhydrochloride salts with a NaOH pellet. Spectroscopic measurements, including ex situ ATR-FTIR, 1D and 2D NMR experiments have been applied to verify the formation of the sodium carbamate adducts (RR′N-CO 2 – Na + ). The emergence of new peaks in the IR spectra ranging between 1702 and 1735 cm –1 together with the chemical shift within 157–158 ppm in the 13 C NMR, as well as with cross-peaks obtained by 1 H- 15 N HSQC measurements at ca. 84 and 6.6 ppm verified the formation of RR′N-CO 2 – Na + products upon the chemical fixation of CO 2 . The CO 2 sorption capacity of the examined biomaterials was evaluated volumetrically, with a maximum value of 8.18 mmol CO 2 ·g –1 sorbent (36.0 (w/w)%, including both chemisorption and physisorption), for 5 (w/v)% solutions measured at 5 bar CO 2 and 25 °C, for TYR and PEA. DFT calculations indicated that the intramolecular hydrogen bonding within the structural motif of EPN-N-CO 2 – Na + adduct provides an exceptional stability compared to monoethanolamine and other structurally related model compounds.

Significant progress has been made in the past decades in the capture, storage, and utilization of greenhouse gases, particularly CO2. In general, the synthesis of most of the available CO2 sorbents is not ecofriendly and can require multistep synthesis in order to prepare and/or activate, which is considered a strict violation of green chemistry principles (GCPs). Therefore, thinking of green frameworks to design chemical products and processes becomes essential to mitigate these challenges. This paper provides an in‐depth review of available green sorbents for CO2 capture with an emphasis on those prepared from biorenewable materials and ionic liquids. A new metric is presented to classify these sorbents based on their degree of compliance to the GCPs, which could be a useful tool in selection of green alternatives. Due to the interdisciplinary nature of this research topic, a wide range of literature is available in multiple areas including but not limited to chemistry and engineering. Hence, this review targets a wide range of scientists including chemists, biotechnologists, material scientists, and meteorologists, as well as green industrial corporations.

Adenine‐Functionalized Dendritic Fibrous Nanosilica as Bifunctional Catalyst for CO₂ Fixation into Cyclic Carbonate

et al. 2023

Cycloaddition of CO2 with epoxide to form cyclic carbonate is one of the most promising approaches to mitigate the rising level of CO2 in the atmosphere. Therefore, the design and synthesis of new materials which can efficiently catalyze such reactions has become an important research area. This article reports on the synthesis of a new material, adenine functionalized dendritic fibrous nanosilica (DAD), by functionalizing the surface of dendritic fibrous nanosilica (DFNS) with an N‐containing heterocyclic nucleobase adenine using a bifunctional isocyanate crosslinker ((EtO)3Si(CH2)3NCO). The surface amine functionalities enable DAD to show selective CO2 adsorption (0.44 mmol/g, at 1 bar CO2 pressure and 298 K temperature) due to acid‐base interaction between CO2 and amine groups. Moreover, DAD efficiently catalyzes the fixation of CO2 with a variety of epoxides into corresponding cyclic carbonates in the presence of TBAB (tetrabutylammonium bromide) co‐catalyst under solvent‐free conditions. The DFNS skeleton of DAD offers a high surface area for enhanced CO2 adsorption, while its organic surface groups, adenine and carbamide, boost the selectivity and activate the epoxide ring and CO2 for cycloaddition reaction. The strong covalent linkage of surface groups in DAD renders robust structural integrity, enabling the catalyst to be recycled multiple times with negligible reduction in its catalytic performance.
