Formation of cyanide-functionalized SBA-15 and its transformation to carboxylate-functionalized SBA-15
Cyanide-functionalized mesoporous silica SBA-15 (CN/SBA-15) with pore diameters larger than 6 nm has been prepared by a one-pot synthesis. The structure of CN/SBA-15 is affected by the amount of the functional silane 2-cyanoethyltriethoxysilane (CTES) and the conditions of co-condensation in the acidic aqueous solution of the triblock copolymer Pluronic P123: whereas direct mixing of the silica...
متن کاملPeriodic mesoporous organosilicas functionalized with a wide variety of amines for CO2 adsorption.
The adsorption of CO2 on amine modified periodic mesoporous organosilicas (PMOs) has been investigated. An ethenylene-bridged PMO is modified with a wide range of diamines and polyamines. A variety of dangling N-containing functionalities, i.e., diaminobutane, diaminohexane, diaminododecane, diethylenetriamine and tetraethylenepentamine, as nucleophiles in a substitution reaction is used. The C...
متن کاملAdsorption of Acid Dyes on Modified Mesoporous SBA-15: Comparison of Two Dyes
In this study, SBA-15-PAMAM mesoporous Nano-adsorbent was synthesized, characterized and applied for adsorption of Acid dyes (Acid Blue 62 (AB62) and Acid Red 266 (AR266)) from aqueous Medias. Adsorption of AB62 and AR266 on SBA-15 ordered mesoporous silica, polyamidoamine functionalized SBA-15(SBA-15-PAMAM), has been investigated. In order to assess the synthesized adsorbent constructional, FT...
متن کاملSynthesis of Cu nanoparticles in mesoporous silica SBA-15 functionalized with carboxylic acid groups.
In this study, the mesoporous silica SBA-15 materials containing carboxylic acid groups were used as an effective support to synthesize Cu nanoparticles. Various Cu loading levels from 4% to 13% on SBA-15 catalysts produced an average particle size of 2.8 to 3.1 nm, regardless of the Cu content.
متن کاملKinetic Study and Equilibrium Isotherm Analysis of Nickel (II) Adsorption onto Alginate-SBA-15 Nanocomposite
The present work was undertaken to evaluate the feasibility of nickel (II) removal from aqueous solution by adsorption onto a biopolymer adsorbent. The adsorbent was prepared using modification of mesoporous silicate SBA-15 with alginate biopolymer (alginateSBA-15) by encapsulation method. Morphological structure of the obtained nanocomposite adsorbent was characterized by XRD, scanning electro...
