“…101–104 This method generally brings about more uniform coating films. Up to now, various types of adsorbents have been coated to substrates, including zeolites, 105 alumina, 106 silica, 107 carbon, 101,108 carbonate, 109 metal–organic frameworks, 110 clay, 111 organic polymers, 112 and so on. The commonly used substrates are ceramic honeycombs, 113,114 metal honeycombs, 115,116 fiber paper, 107 and polymer monoliths.…”

“…Microporous polycarbazole, which possessed an electron-rich scaffold, showed an excellent uptake capacity for carbon dioxide and good selectivity toward CO 2 over N 2 [41]. Enhanced sorption capacity toward CO 2 (4.9 mmol•g −1 ) under 367 K and 1 bar partial pressure of CO 2 was measured for a ceramic material coated with MgO/carbon nanofibers composite [42].…”

Adsorption methods for CO2 capture are characterized by high selectivity and low energy consumption. Therefore, the engineering of solid supports for efficient CO2 adsorption attracts research attention. Modification of mesoporous silica materials with tailor-made organic molecules can greatly improve silica’s performance in CO2 capture and separation. In that context, a new derivative of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, possessing an electron-rich condensed aromatic structure and also known for its anti-oxidative properties, was synthesized and applied as a modifying agent of 2D SBA-15, 3D SBA-16, and KIT-6 silicates. The physicochemical properties of the initial and modified materials were studied using nitrogen physisorption and temperature-gravimetric analysis. The adsorption capacity of CO2 was measured in a dynamic CO2 adsorption regime. The three modified materials displayed a higher capacity for CO2 adsorption than the initial ones. Among the studied sorbents, the modified mesoporous SBA-15 silica showed the highest adsorption capacity for CO2 (3.9 mmol/g). In the presence of 1 vol.% water vapor, the adsorption capacities of the modified materials were enhanced. Total CO2 desorption from the modified materials was achieved at 80 °C. The obtained silica materials displayed stable performance in five CO2 adsorption/desorption cycles. The experimental data can be appropriately described by the Yoon–Nelson kinetic model.

“…Furthermore, to the best of our survey revealed that the majority of the nanotubes such as MgO nanotubes, BN nanotubes, SiC nanotubes and ZnO nanotubes were not investigated as candidates for CO 2 capture. Meanwhile, the CO 2 absorption of two-dimensional and doped forms of these compounds was rarely reported [6,7].…”

This study addressed the nano-mechanism of CO2 capture by Al-doped, B-doped and N-doped single-walled silicon carbide nanotubes (SWSiCNTs) using the prominent density functional theory. The results showed absolute interactions between CO2 and B- and N- impurity atoms of the SWSiCNT surface with the highest adsorption energy of −1.85 eV and −1.83 eV respectively. Analysis of the binding energy of CO2 to Al-doped SWSiCNT revealed that chemisorption between them is stronger than B-doped and N-doped SWSiCNTs. Results from optical adsorption spectra revealed that both B-and N-doped systems adsorb CO2 in the visible region of the electromagnetic spectrum while B-doped SiCNT shows the highest adsorption. This study recommends B- and N-doped SiCNTs as candidates for CO2 capture and storage with higher efficiency by B-doped SiCNT, while the performance of the Al-doped system was underscored.
