    Abstract:

    Using sol-gel method, the iron-containing nanocomposites with the ferric citrate as iron raw were synthesized. The clear sols were gelated at room temperature and then treated at 60 oC in vacuum to get dry gels which were characterized by thermogravimetricSanalysis (TG). Finally, mesoporous Fe2O3/SiO2 nanoparticles were obtained by the calciner at 400 oC for 3h. The structural properties of synthesized particles were investigated by X-ray diffraction (XRD), N2 adsorption-desorptionStechnique, transmission electron microscopy (TEM), Fourier-transform IR spectroscopy (FT-IR), and Temperature programmed reduction (H2-TPR), which revealed that the iron active centers were successfully incorporated into the silica framework with spherical particles size about 50 nm and a average pore diameter of 30-45 ?. The catalytic activity of nanocatalysts had been tested in the synthesis diphenylmethane by Friedel-Crafts alkylation reaction. It found that the catalysts exhibited an excellent activity with 100% conversion of benzyl chloride and relatively higher selectivity to diphenylmethane, and could be reusedSmultiple times.
