“…In the same way, Shah et al (2017) [55] have also intercalated the poly (amido amine) dendrimer in a mica and a montmorillonite, being efficient only in the latter case. The presence of the dendrimer enhances the CO 2 adsorption capacity; however, the strength of the interaction between the dendrimer and CO 2 also increases, so that the regeneration of the adsorbent requires more severe conditions [55,56].…”

The aim of this work is to make a brief review of the adsorption of CO2 on modified clay minerals. Previous researchers have used different clay modifications, either by making changes in the structure by a reaction with another product or by the addition of a catalyst to improve their CO2 adsorption capacity. In order to obtain high values of CO2 uptake, some researchers have been incorporated amines-speices such as (3-aminopropyl)triethoxysilane (APTES), tetraethylenepentamine (TEPA) and a branched polyethylenimine (PEI) by grafting or impregnation. The synthesis of an adsorbent from mineral clays can generate an increase in its porosity and in its textural properties. These investigations differ in a number of factors such as the kind of clay, the operating conditions, y and the nature of the impregnated compound. The role of these factors in the CO2 adsorption capacity will be considered in detail in this review.

“…1,2,11,12 PAMAM or carbosilane dendrimers can be used to accomplish such developments by adsorbing to surfaces via "graing to" or "graing from" [13][14][15][16][17][18][19] procedures. The formation of PAMAM monolayers on solids has been discussed by Crooks and others, 20,21 and a polyphenylene dendrimer monolayer formed using the electrospray method has been reported recently. [22][23][24] Despite progress in the development of dendrimer-modied sorbents, information on specic surface areas (SSAs) of dendrimers in the solid state is very limited.…”

“…Different types of dendrimeric molecules have already been grafted on to silica, and a few examples of dendrimers used for trapping CO 2 have been recently presented: the use of poly(propyleneimine) (PPI) dendrimers included but not grafted on to silica for trapping CO 2 during the purification of gases and for CO 2 capture, and the use of polyol hyperbranched polymers in Mg/Al hydroxides for the reversible trapping of CO 2 . PAMAM dendrimers bound to organoclays, PPI dendrimers intercalated inside graphite oxide, triazine dendrimers alone or triazine dendrons grafted on to silica have also been proposed for trapping CO 2 .…”
