Adsorption of L-Histidine onto Functionalized Mesoporous SBA-15 Organosilicas

Abstract

Adsorption of L-histidine (LH) over mesoporous SBA-15 silicas functionalized by amine-, thiol-and cyano-functional groups has been studied. These organosilicas have been synthesized by co-condensation of proper monomers in the presence of a template (Pluronic P-123), and characterized by elemental analysis, nitrogen adsorption, X-ray diffraction and transmission electron microscopy. The highest LH static adsorption capacity was observed for the cyano-functionalized sample [approximately 70 mg g -1 (450 mol g ).

The Isomerization of Limonene over the Ti-SBA-15 Catalyst—The Influence of Reaction Time, Temperature, and Catalyst Content

“…However, the undoubted advantage of this material is the presence, apart from the hexagonally arranged mesopores, of significantly smaller pores that account for more than 70% of the surface area of this material. These micropores are located in the walls of this type of material and are a combination of ordered main pores [32]. The advantage of SBA-15 is not only the unique construction of this material and better stability of its structure but also the possibility of a safe application of this material because it does not exhibit toxicity.…”

Functionalization of mesoporous silica surface with carboxylic groups by Meldrum’s acid and its application for sorption of proteins

“…So far many functional groups have been used to modify the silica surface by both one-pot co-condensation and post-synthesis grafting including amine [16][17][18][19], cyano [20,21], thiol [2,[22][23][24], vinyl [25][26][27], phenyl [20,26,28], alkyl [29][30][31][32] and many others. Some studies have also focused on the functionalization with carboxylic groups [33][34][35][36][37][38].…”
