The Titanium and Mixed Titanium Carbon Nanoparticles Supported on Silica for Cyclohexene Conversion and of Dyes Removal
Abstract
The two samples of nanoparticles sulfated titania over silica ST/SiO2 and sulfated titania active carbon over silica STAC /SiO2 were synthesized by sol- gel method and characterized by X-ray diffraction XRD , BET , thermal analysis and TEM spectroscopy . The TEM demonstrated that the average particle size of two samples were found to be in the range of (15-50 nm).The ST/SiO2 and STAC/SiO2 have been used as an effective catalyst for cyclohexene disproportionation which STAC/SiO2 catalyst show much higher selectivity for benzene formation at temperature ranging from 200-280°C. Series of kinetic studies had been conducted for the removal of acid and basic dyes. The STAC/SiO2 has a considerable potential as an adsorbent for the removal of acidic dye (eosin) than the basic dye (saffranin).
Keywords: ST/SiO2 and STAC/SiO2 nanocatalyst, Sol- Gel method ,cyclohexene and dyes.
