“…The higher the energy of active sites, the stronger CO 2 interacts with the sites and remains trapped. Recently, zeolites are reported as efficient CO 2 adsorbents thanks to their size, charge density, and tunable chemical composition (Jiang et al 2018;Yu et al 2018). Hydrotalcite-based materials are thereby interesting alternative materials to zeolites, as their chemical composition can also be finely tuned.…”

“…Many researchers have been committed to developing solid sorbents recent years. Porous solids, such as zeolites, active carbon, mesoporous silica, such as SBA‐12, SBA‐15, SBA‐16, MCM‐41, and metal organic frameworks (MOFs) are good candidates for capturing CO 2 . Especially, the amines immobilized porous solid sorbents have been an increasing focus.…”

“…In this type of separation technology, the components of a gas mixture are separated by their molecular characteristics and affinity to an adsorbent material. For this purpose, a variety of materials have been studied including zeolites [7][8][9], carbon molecular sieves (CMS) [10][11][12], metal organic frameworks (MOFs) [13][14][15] and activated carbons (ACs) [16][17][18]. Among these materials, activated carbons present advantages in terms of: (i) hydrophobicity; thus, there is no need for a drying step before upgrading; (ii) low heat of adsorption, therefore a low energy of regeneration; (iii) the possibility of heteroatoms' functionalization to modify their adsorption behavior; and (iv) high CO 2 adsorption capacity at ambient pressure [19].…”
