Adsorption of CO2 by a novel zeolite doped amine modified ternary aerogels

Fabrication of new in‐situ ternary nano/microcomposite LDH/Ag2O/Bayerite in trimetallic NiAg/Al layered double hydroxides for CO2 capture material

“…The primary aspect to evaluate is the state of the flue gas, encompassing its composition, temperature, moisture content, flow velocity, and concentration of carbon dioxide. [7][8][9] Solid adsorbents are preferred over other CO 2 adsorbents, such as liquid materials, because they can operate at a wide range of temperatures, require minimum energy, and have good chemical or thermal stability. 10,11 Various solid adsorbents, such as porous carbons, 12 metal oxides, 13 zeolites, 14 metal-organic frameworks, 15 and porous polymers, 16 have been produced to capture CO 2 .…”

“…The unique emission parameters determine the most appropriate method for capturing CO 2 from significant emission sources, such as adsorption, absorption, and membrane separation. The primary aspect to evaluate is the state of the flue gas, encompassing its composition, temperature, moisture content, flow velocity, and concentration of carbon dioxide 7–9 . Solid adsorbents are preferred over other CO 2 adsorbents, such as liquid materials, because they can operate at a wide range of temperatures, require minimum energy, and have good chemical or thermal stability 10,11 .…”

Synthesis, Characterization and Gas Adsorption of Unfunctionalized and TEPA-Functionalized MSU-2

“…In order to ensure high CO 2 adsorption capacity, a suitable adsorbent needs to have a high affinity with the targeted gas [16], large and tunable pore sizes, a large total pore volume, a high specific surface area, and a multidimensional porous framework [17]. The types of materials which have been studied for use as CO 2 adsorbents include carbons [18], oxides (for example, ZnO) [19], metal organic frameworks (MOFs) [20], zeolites [21] and mesoporous silicas such as MCM-41, SBA-16, MSU-J, KIT-6, and MSU-1 [22][23][24][25][26]-all of which show high potential for CO 2 adsorption as they exhibit the desired characteristics of a good adsorbent, as mentioned above. In addition, mesoporous silicas contain a large amount of silicon hydroxyl groups on the surface, which can facilitate further surface modifications through the formation of chemical bonds with the added organic materials [27].…”
