Preparation of silica aerogels using CTAB/SDS as template and their efficient adsorption

Organic–inorganic hybridization for the synthesis of robust in situ hydrophobic polypropylsilsesquioxane aerogels with fast oil absorption properties

“…29 The strong T 3 and Q 4 peaks, combined with the weak Q 3 and T 2 peaks, revealed a high degree of condensation of PTES and TEOS. 45 Based on the 29 Si NMR and FTIR analyses, the molecular structure of PSA-7 was proposed. As assumed, -C 3 H 7 groups distributed uniformly in the network of PSA-7 with few uncondensed -OH groups bonded to Si atoms.…”

A novel silica xerogel synthesized from volcanic tuff as an adsorbent for high‐efficient removal of methylene blue: parameter optimization using Taguchi experimental design

“…Silica aerogels are synthesized using sol–gel method under supercritical drying conditions once after hydrolysis and condensation reaction of silica precursors like tetraethylorthosilicate (TEOS), tetramethylorthosilicate (TMOS), polyethoxydisiloxane (PEDS), methyltriethoxysilane (MTES), methyltrimethoxysilane (MTMS), and so on . In the large scale production of aerogels, supercritical drying is such an energy‐cost process and dangerous as it requires high temperature and pressure . To overcome these problems, the synthesis of silica xerogels has been promoted for large production at ambient pressure drying .…”

“…18,19 In the large scale production of aerogels, supercritical drying is such an energy-cost process and dangerous as it requires high temperature and pressure. 20,21 To overcome these problems, the synthesis of silica xerogels has been promoted for large production at ambient pressure drying. 22 Furthermore, low cost silica precursors such as fly ash, 23 kaolin, 24 oil shale ash, 25 rice hull ash, 26 bagasse ash, 27 corn stalk, 28 wheat starch 29 and cellulose 30 have been preferred instead of the expensive alkoxides, nowadays.…”

Cluster–cluster aggregation with mobile impurities

“…The possibilities of control pore shapes and pore distributions include the use of template to tailor the system and open porous structure. In fact, it has been demonstrated that the use of template can affect the pore structure and their orientation [6][7][8][9].…”

“…One of the commonly used procedure for the fabrication of these materials is the sol-gel technique. In the last decades, surfactants started to be included in the solution for the corresponding material preparation, because they allow some control on the pore structure of the resulting objects [6,7]. The surfactants form micelles which act as inert template during the monomer aggregation process until a macroscopic cluster is formed.…”
