The Synthesis and Characterisation of Ordered Mesoporous Materials Incorporating Organo-Siloxanes

Abstract

AbstractOrganically-functionalized mesoporous silicas have been prepared at room temperature, in a base-catalysed reaction, by the co-condensation of tetraethoxysilane and organosiloxanes ((C2H5O)3Si-R; R = C6H5 or n-C8H17) in the presence of surfactant (C16H33N(CH3)3Br) templates. The resulting materials are covalently linked, hexagonally ordered, hybrid inorganicorganic networks.
