Carbon dioxide emissions cause global warming, and greenhouse gases and climate change are very serious problems. Mesoporous silica material SBA-15 has been preferred mostly as an ideal adsorbent for CO2 due to its excellent properties such as high surface areas and pore volumes, larger pore diameter, and thicker silica wall. In the literature studies, SBA-15 has been modified by different functional groups and the effects of modification methods on the CO2 adsorption have been investigated. Modified SBA-15 adsorbents showed high CO2 adsorption capacity. The aim of this chapter is to review the use of modified-SBA-15 mesoporous silica materials as adsorbent for CO2 capture.

Electrospinning techniques have become an efficient way to produce continuous and porous carbon nanofibers. In view of CO2 capture as one of the important works for alleviating global warming, this study intended to synthesize polyacrylonitrile (PAN)-based activated carbon nanofibers (ACNFs) using electrospinning processes for CO2 capture. Different structures of PAN-based ACNFs were prepared, including solid, hollow, and porous nanofibers, where poly(methyl methacrylate) (PMMA) was selected as the sacrificing core or pore generator. The results showed that the PMMA could be removed successfully at a carbonization temperature of 900 °C, forming the hollow or porous ACNFs. The diameters of the ACNFs ranged from 500 to 900 nm, and the shell thickness of the hollow ACNFs was approximately 70–110 nm. The solid ACNFs and hollow ACNFs were microporous materials, while the porous ACNFs were characterized by hierarchical pore structures. The hollow ACNFs and porous ACNFs possessed higher specific surface areas than that of the solid ACNFs, while the solid ACNFs exhibited the highest microporosity (94%). The CO2 adsorption capacity on the ACNFs was highly dependent on the ratio of V<0.7 nm to Vt, the ratio of Vmi to Vt, and the N-containing functional groups. The CO2 adsorption breakthrough curves could be curve-fitted well with the Yoon and Nelson model. Furthermore, the 10 cyclic tests demonstrated that the ACNFs are promising adsorbents.

Mesoporous silica and organosilica materials are a class of nanostructured materials that have porous structures with tunable nanometer pores, large surface areas, high pore volumes, and, in some cases, well-ordered mesostructures. Furthermore, in the case of mesoporous organosilicas, the materials possess various types of organic functional groups. This review highlights the different synthetic methods developed for mesoporous silica and organosilica nanomaterials. The review also discusses the various synthetic strategies used to functionalize the surfaces of mesoporous silica materials and produce highly functionalized mesoporous materials. Rational design and synthetic methods developed to place judiciously chosen one or more than one type of functional group(s) on the surfaces of mesoporous silica materials and generate monofunctional and multifunctional mesoporous silica materials are also introduced. These organic functionalization methods have made possible the synthesis of organically functionalized mesoporous silicas and mesoporous organosilicas with various interesting properties and many potential applications in different areas, ranging from catalysis to drug delivery and biosensing.
