Effect of β-cyclodextrin Attendance on Hexagonal Ordering of MCM-41 Silicas

Year: 2014

Type: article

Abstract: Hydrothermal sol-gel synthesis of hexagonally ordered silicas using a hybrid template system is reported. Hybrid template system was made from ionic surfactant (cetyltrimethylammonium bromide or decyltrimethylammonium bromide) and supramolecular porogen β-cyclodextrin. Tetraethylorthosilicate or its blend with 3-(chloropropyl)triethoxysilane were used as matrix precursors. Synthesized silicas were characterized by IR spectroscopy, X-ray diffraction techniques as well as transmission electron microscopy. It was shown that the hexagonal structure of MCM-41 is not changed despite the addition of β-cyclodextrin.
