Abstract:
Template-directed co-condensation was used to synthesize phenyl-modified MSU-1 and bi-functionalized MSU-1 silica containing binary moieties of covalently linked phenyl along with methyl or ureidopropyl [H 2 NCONH(CH 2 ) 3 ]. The texture properties of these materials from x-ray diffraction, Fourier transform infrared, nuclear magnetic resonance, scanning electron microscopy, high-resolution transmission electron microscopy, N 2 adsorption, thermogravimetric analysis data, varied with the type of alkoxylsilane precursor and the amount of organosiloxane in the mixture. Small-angle x-ray scattering results, for the as-synthesized and surfactant-extracted organo-modified MSU-X, showed that the templates remaining in the mesostructures gave positive deviation from Porod's law while the incorporated organic groups led to a negative deviation, which formed an interfacial layer between the pore and silica matrix.
