Title: Studies Of Mcm-41 Obtained From Different Sources Of Silica
Author: Paulino I.S.
Schuchardt U.
Abstract: An efficient and simple method has been used to synthesize MCM-41 at room temperature under stirring. The mesoporous materials were obtained using three different silica sources, tetramethoxysilane (TMOS), tetraethoxysilane (TEOS), tetrapropoxysilane (TPOS), ammonium hydroxide and cetyltrimethylammonium bromide (CTMABr) as template, in various reaction times The route of the synthesis was monitored by X-ray diffraction (XRD) which showed that a highly ordered mesoporous material was obtained after just 15 min. The effect of the silica source on the properties of the MCM-41 samples obtained is also discussed wing nitrogen sorption and X-ray diffraction.
