Synthesis of mesoporous silica grafted with 3-glycidoxypropyltrimethoxy-silane
چکیده انگلیسی
Hexagonal mesoporous silicas chemically modified with 3-glycidoxypropyltrimethoxy-silane functional groups were synthesized through the post-synthesis of surfactant free mesoporous silica (OSU-6-W). The solid state 29Si NMR, titration method and elemental analysis of the modified samples showed that the average number of pendant groups in these hybrids were around 2.17 and 3.49 group/nm2, respectively. The surface area analysis showed that these materials have pore diameters of 40.7 and 33.2 Å and surface areas of 966 and 720 m2/g, respectively. Infrared spectroscopy, solid state NMR for 13C and 29Si nuclei and X-ray diffraction patterns are in agreement with the success of the proposed synthetic procedures, as confirmed for the formation of the mesoporous hybrids. They have shown good performance towards metal-ion adsorption.
