“…Compared with the conventional CO 2 capture process using amine scrubbing, the novel solid sorbent-based process offers several potential advantages such as low equipment corrosivity, less toxicity, and cost-effective regenerability of the sorbent that can be expected to significantly lower the energy input during regeneration and overcome the issues associated with the use of traditional aqueous amine sorbents [26,27]. …”

“…However, this system was specifically effective at a site where waste steam was available [27]. Thus, most of the studies on VSA systems are solid sorbents with physisorption mechanisms such as zeolites [30,31], activated carbons [32,33,34] and metal-organic frameworks [26,35], having large CO 2 capture capacities (3.8–8.6 mmol·g −1 at 0 to 20 °C) in the low pressure region up to 1 bar, and currently they are under development. …”

Microporosity and CO2 Capture Properties of Amorphous Silicon Oxynitride Derived from Novel Polyalkoxysilsesquiazanes

et al. 2018

Polyalkoxysilsesquiazanes ([ROSi(NH)1.5]n, ROSZ, R = Et, nPr, iPr, nBu, sBu, nHex, sHex, cHex, decahydronaphthyl (DHNp)) were synthesized by ammonolysis at −78 °C of alkoxytrichlorosilane (ROSiCl3), which was isolated by distillation as a reaction product of SiCl4 and ROH. The simultaneous thermogravimetric and mass spectrometry analyses of the ROSZs under helium revealed a common decomposition reaction, the cleavage of the oxygen–carbon bond of the RO group to evolve alkene as a main gaseous species formed in-situ, leading to the formation of microporous amorphous Si–O–N at 550 °C to 800 °C. The microporosity in terms of the peak of the pore size distribution curve located within the micropore size range (<2 nm) and the total micropore volume, as well as the specific surface area (SSA) of the Si–O–N, increased consistently with the molecular size estimated for the alkene formed in-situ during the pyrolysis. The CO2 capture capacity at 0 °C of the Si–O–N material increased consistently with its SSA, and an excellent CO2 capture capacity of 3.9 mmol·g−1 at 0 °C and CO2 1 atm was achieved for the Si–O–N derived from DHNpOSZ having an SSA of 750 m2·g−1. The CO2 capture properties were further discussed based on their temperature dependency, and a surface functional group of the Si–O–N formed in-situ during the polymer/ceramics thermal conversion.

“…Very recently Zhi reported a transition-metal-free carboxylation of C(sp 2 )-H bond with CO2 followed by a lactonization reaction applied to 2-(imidazo[1,2-a]pyridine-2-yl)phenol (154, Scheme 65) and 2-(1-arylvinyl)phenol derivatives (82, Scheme 66) [144]. The author proposes that sodium 2,4,6-trimethylphenoxide (153), formed in situ from 2,4,6-trimethylphenol and NaH, plays a role as CO 2 -carrier. A large body of evidence suggests that only "fixed CO 2 " (absorbed or adsorbed) by the solid reagent is involved in the carboxylation reaction, therefore 2,4,6-trimethylphenoxide may increase the amount of CO 2 able to react being inert towards ortho-carboxylation itself (Scheme 64).…”

“…Furthermore, very recently porous MOF have been used as efficient heterogeneous catalysts in carboxylation of terminal alkynes with CO2. Considering that MOF have emerged as promising porous materials with a wide range of applications encompassing CO2 capture, separation, storage and regeneration as well as CO2 photo-and electro-catalytic reduction, future directions in MOF chemistry point at their use in CO2-epoxides co-polymerization (to make commodity polymers) and in CO2-olefins co-polymerization [153].…”

This review focuses on recent advances in the field of direct carboxylation reactions of C(sp 3 )-H and C(sp 2 )-H bonds using CO 2 encompassing both transition-metal-catalysis and base-mediated approach. The review is not intended to be comprehensive, but aims to analyze representative examples from the literature, including transition-metal catalyzed carboxylation of benzylic and allylic C(sp 3 )-H functionalities using CO 2 which is at a "nascent stage". Examples of light-driven carboxylation reactions of unactivated C(sp 3 )-H bonds are also considered. Concerning C(sp 3 )-H and C(sp 2 )-H deprotonation reactions mediated by bases with subsequent carboxylation of the carbon nucleophile, few examples of catalytic processes are reported in the literature. In spite of this, several examples of base-promoted reactions integrating "base recycling" or "base regeneration (through electrosynthesis)" steps have been reported. Representative examples of synthetically efficient, base-promoted processes are included in the review.
