Organic-inorganic hybrid nanoporous materials with silicalite-1 structure were
synthesized in one step co-condensation technique and subsequent transformed into solid acid
materials. The tetraethoxysilane (TEOS) was used as the primary inorganic silica source with the
phenethyltrimethoxysilane (PE) as an organic modifier. The effect of the PE presence in the initial
synthesis mixture was studied by varying the molar ratio of PE to TEOS in the range of 0.05 to 0.20.
The resulting organic-inorganic hybrid materials were characterized for its crystallinity (X-ray
diffraction, XRD), surface morphology (scanning electron microscopy, SEM) and elemental
composition (elemental analysis). The degree of chemical interactions between the organic and
inorganic phases was determined by Fourier transform infrared spectroscopy (FTIR). The acid
strength of the organic-inorganic hybrid solid acid materials was also obtained by titration
technique.
