Direct synthesis of thiol-ligands-functionalized SBA-15: Effect of 3-mercaptopropyltrimethoxysilane concentration on pore structure

Hybrid surfactant-templated mesoporous silica formed in ethanol and its application for heavy metal removal

“…"Hydrothermal-synthesis" process is a common method to prepare mesoporous materials [6,7]. This method requires organic and inorganic reactants combining in the water phase, which easily results in faster hydrolysis of organosilane and reduces the cross-linking degree of organosilane and silica framework as well as intake of functional groups.…”

Amine Catalyzed Atomic Layer Deposition of (3-Mercaptopropyl)trimethoxysilane for the Production of Heterogeneous Sulfonic Acid Catalysts

“…At 60 cycles, the highest cycle number tested, the MP density is 4.59 µmol/m 2 , a value comparable to that seen with cocondensation, and improved over that of grafting. 25 Following the characterization of the ALD process, the 60 cycle material was chosen as a representative sample and compared with a sample which was functionalized with mercaptopropyl groups though a toluene reflux grafting method. The same substrate was used, so that the differences in structural properties resulting from the two preparation methods could be analyzed.…”

A facile method for preparing thiocyanato-functionalized porous silica nanospheres

“…Anwander et al, 2000;Yao et al, 2005;Wei et al, 2005;Choi et al, 2005;Lin et al, 2009;Zarabadi-Poor, Badiei, Fahlman, Arab, & Ziarani, 2011;Han, Chen, Wang, Gao, & Che, 2011;Vathyam et al, 2011;Liu, Yan, Zhang, Yang, & Bai, 2012). In the former method, organic functional groups are directly grafted onto the surface of porous silica materials.…”
