Preparation and characterization of hydrophilic organo-montmorillonites through incorporation of non-ionic polyglycerol dendrimers derived from soybean oil

Dendrimers: syntheses, toxicity, and applications toward catalysis, environmental sciences, and nanomedecine

“…[8][9][10][11][12][13][14][15][16][17] The intrinsic properties of the dendritic organic moiety 10,[18][19][20] are designed according to the targeted applications [21][22][23][24] or to confer specific features to the hybrid materials when supported on inorganic supports. [25][26][27][28][29][30][31][32][33][34] In the area including energy and green chemistry, recently, major advances have been made in this regard by synthesizing metalorgano-aluminosilicates through in-situ synthesis of metal nanoparticles within the entanglements of supported dendrimers. 35 The development of the new concept of "Truly Reversible Gas Capture" by clay-dendrimer based adsorbents that do not need thermal regeneration has particularly attracted attention.…”

“…35 The development of the new concept of "Truly Reversible Gas Capture" by clay-dendrimer based adsorbents that do not need thermal regeneration has particularly attracted attention. 26,27,[29][30][31]36 This concept has not been thoroughly examined until recently and opens new prospects for medical, agricultural, and industrial applications involving catalysis and adsorption.…”

Improved carbon dioxide storage over clay-supported perhydroxylated glucodendrimer

“…16 Clay materials 13,14,[17][18][19] long with zeolites and analogous adsorbents [20][21][22][23] are now the focus of growing interest due to both of their intrinsic and induced affinity towards CO 2 . 24 The latter strongly correlates to the chemical composition, and can be improved either by purification for removing acidic impurities, if any, or insertion of organic moieties bearing several hydroxyl groups.…”

“…13,14,[17][18][19] Nevertheless, due to the hydrophilic nature of clay materials, uniform incorporation of hydrophobic polymers still remains a major challenge to be addressed, more particularly for high concentration or for high molecular weight entities. Interestingly however, dendrimeric architectures, particularly those made of a dense core and possessing a large number of surface OH groups at lower generation 34 such as glycodendrimers, [35][36][37][38] may constitute a major improvement.…”

“…Among these, alkali and alkaline earth metal carbonates, alkali metal hydroxides, polyols in liquid phase, or supported on solid surfaces have been systematically explored. 13 Supported alcohols showed lower but interesting affinity towards CO 2 , involving instead, only weakly bonded carbonate-like associations that allow much easier gas release than carbamate-like bonding even at room temperature and under forced convection. [14][15] Actually, the estimated binding energy between ethanol and CO 2 has been estimated at 0.84 kcal/mol 16a and the direct binding of cyclodextrin's OH group and CO 2 was further confirmed by CP/MAS 13 C-NMR spectroscopy.…”
