“…39 The CO 2 adsorption capacity increases linearly with the total pore volume of the SBA-15 phase, while no evident correlation between pore size and adsorption capacity was found as reported by Yan et al 40 The amine loaded in SBA-15 dispersed more uniformly than MCM-41 due to the advantages of unique 2D hexagonal structure and large pores of SBA-15. 41 Popa et al 42 used different micelle swelling agents (1-phenyldecane, butylbenzene, and mesitylene) to prepare macroporous ordered SBA-15 with a pore size up to 10 nm. The adsorption capacity of the 3aminopropyltriethoxysilane grafted SBA-15 sample is 3.58 mmol g −1 at 50 °C in a gas mixture of 30% CO 2 /N 2 .…”

In the past decades, huge developments in rational design, synthesis, and application of solid amine CO2 adsorbents have been reported. Since the reports on polyethylenimine impregnated silica adsorbents, there has been tremendous growth in this area along with the increase of supported amine adsorbent related publications. Owing to high adsorption capacity, a facile synthesis procedure and low cost, amine-functionalized silica adsorbents demonstrate great promise for CO2 capture technologies. To push their industrial application forward, their stability must be improved further to mitigate acidic impurities and CO2, O2, and thermal-induced deactivation. Furthermore, fundamental understanding of the relationship between amine / support structure and adsorption performance is needed to guide the design of stable amine silica adsorbents. This review summarizes recent research that mainly focuses on important roles of support and amine structure in CO2 adsorption performance and improved stability. The recent progress in promising reactor design for solid amine adsorbents is discussed to provide insights on developing the continuous CO2 capture process for separating CO2 from flue gas and ambient air.

“…Nowadays, CO 2 adsorption studies based on amine functional groups have been intensively and extensively performed. Various materials with a high specific surface area such as zeolite [9][10][11], activated carbon [12][13][14][15], metal-organic frameworks (MOFs) [16][17][18][19], and porous silica [20][21][22][23] have been demonstrated. When an amine functional group meets carbon dioxide gas in the presence of moisture, a carbamate salt and a hydrogen carbonate salt are formed.…”

Facile Synthesis of Mesoporous Silica at Room Temperature for CO2 Adsorption

et al. 2022

Although mesoporous silica materials have been widely investigated for many applications, most silica materials are made by calcination processes. We successfully developed a convenient method to synthesize mesoporous materials at room temperature. Although the silica materials made by the two different methods, which are the calcination process and the room-temperature process, have similar specific surface areas, the silica materials produced with the room-temperature process have a significantly larger pore volume. This larger pore volume has the potential to attach to functional groups that can be applied to various industrial fields such as CO2 adsorption. This mesoporous silica with a larger pore volume was analyzed by TEM, FT-IR, low angle X-ray diffraction, N2-adsorption analysis, and CO2 adsorption experiments in comparison with the mesoporous silica synthesized with the traditional calcination method.

“…[27] Amine functionalized SBA-15 has been used in the hydrogenation of CO 2 to formic acid, reusing and activity for CO 2 cycloaddition onto oxiranes. [28][29][30][31] There are a number of research work published on amine functionalized mesoporous silica that are used on the application of various catalytic reactions like enantioselective hydrogenation of α-keto ester, aldehyde hydrogenation, CO 2 capture etc. [32][33][34][35] Candida antarctica lipase B was immobilized on amine modified MCM-41 and their application on transesterification of soybean oil and phytosterol [36] is also reported.…”

Amine and Sulfonic Acid Anchored Porous Silica as Recyclable Heterogeneous Catalysts for Ring‐Opening of Oxiranes

et al. 2022

MCM type mesoporous silica materials can be used as potential catalysts with appropriate functionalization, for increasing selectivity and yield of the desired products. Co‐condensation or post‐synthesis treatment is the most common process of surface functionalization of mesoporous materials for the introduction of catalytic groups to their internal pore surfaces. In this work two different functional moieties were introduced on the surface of mesoporous material; one, a base functional group (3‐aminopropyl)triethoxysilane (APTES) and another, an acid functional group (3‐mercaptopropyl)triethoxysilane (MPTES). The materials were characterized thoroughly by powder XRD, BET, FT‐IR, TGA, NMR, SEM, TEM, etc. The results confirmed successful grafting of both the functional groups. The functionalized materials were tested in ring opening of different oxiranes; and the base functionalized MCM‐48 was found to be catalytically more active than acid functionalized material and was correlated mechanistically. Conversion of morpholine and piperidine with base functionalized material was found to be 93 and 91 %, respectively; and with acid functionalized material, 52 % of conversion of morpholine and 57 % conversion of piperidine was observed. Amine modified mesoporous MCM‐48 and MCM‐41 were found to be totally heterogeneous in nature and the catalysts were reusable up to 4 times without leaching.
