Evaporation-Induced Self-Assembly of Hybrid Bridged Silsesquioxane Film and Particulate Mesophases with Integral Organic Functionality

Abstract

Since the discovery of surfactant-templated silica mesophasesl, the development of organic modification schemes to impart functionality to the pore surfaces has received much attention2-13. Most recently, using the general class of compounds referred to as Here we use an evaporation-induced self-assembly procedure20 to prepare BSQM films and spherical nanoparticles.

Titania/C TAB Nanoskeleton as adsorbent and photocatalyst for removal of alkylphenols dissolved in water

“…For example, activated carbon is one the most popular sorbent materials to extract chemical contaminants from wastewater. In recent years, organic/inorganic hybrid porous materials such as organic molecules-grafted mesoporous materials have attracted attention as effective adsorbents for removal of organic contaminants from water [5][6][7][8][9][10][11][12][13]. In addition, several reports describe that mesoporous silica materials (MCM-41) containing surfactant template also act as effective adsorbents for the removal of organic contaminants from aqueous solutions [14][15][16][17][18][19][20][21].…”

Aerosol-assisted synthesis of mesoporous organosilica microspheres with controlled organic contents

“…We demonstrated the facile preparation of PMO with different organic contents in the frameworks by changing the BTSE/TEOS molar ratios of initial precursor solutions. To the best our knowledge, a systematical study focusing on the control of organic contents has not been reported thus far, though several spray-dried mesoporous materials with different compositions have been designed by adjusting the composition of precursor solutions [23][24][25][26][27][28][29][30][31][32][33][34]. We demonstrated here that ethane and benzene fragments were successfully embedded in the frameworks (up to a BTSE/TEOS molar ratio of 0.50) with the formation of ordered mesoporous structures.…”

“…silica [23][24][25][26][27], organosilica [28][29][30], maghemite-organosilica [31], carbon [32] and metal oxide [33]) have been prepared by spray drying (i.e. aerosol-assisted process) [34].…”

“…clear precursor solution) is sprayed through a nozzle into a hot steam gas, in which the supplied liquid is vaporized and droplets are dried immediately. The system used previously is not suitable for the continuous production of solids, because dried samples are collected using membrane filters [23][24][25][26][27][28][29][30][31][32][33][34]. Recently, we developed a laboratory-made apparatus suitable for rapid mass production and industrial uses [35][36][37][38][39].…”

Formation of Ordered Silica-Organic Hybrids by Self-Assembly of Hydrolyzed Organoalkoxysilanes with Long Organic Chains

“…Because simple sol-gel reactions of alkoxysilanes usually result in the formation of amorphous materials [4], much efforts have been made in the structural control on a nanometer-length scale [5][6][7][8]. Such an attempt is of great interest from the possibility to produce novel hybrid materials with unique structures and properties.…”
