Fabrication Fe3O4/SiO2/TiO2 Nanocomposites and Degradation of Rhodamine B Dyes under UV Light Irradiation

Recycling and reusing of catalyst is an important factor to produce capable and low cast catalysts. silica coated magnetic nanoparticles (fe3o4/sio2) were synthesized via a simple sol-gel method with the aid of sonication. fe3o4 nanoparticles. after that a layer of tio2 was constricted by hydrolyze and condensation of teteranormalbuthyltitanate to produce fe3o4/sio2/tio2 nanocompsite. as-synthesized nanparticles were characterized with x-ray powder diffraction, fourier-transform-infrarotspektrometer, transition electron microscopy and scanning electron microscopy. in this study, a new kind of fe3o4/sio2/tio2 photocatalyst was prepared with the purpose of using light and inhibiting the recombination of electrons and holes. in situ treatment of rhdamine b in water was performed using this fe3o4/sio2/tio2 photocatalyst. the purpose of this research was to provide a new method and the basic data for the removal of organic pollutants in water. fe3o4/sio2/ tio2 nanocomposite showed enhanced photocatalytic properties as evidenced by the enhanced photodegradation of rhodamine b under ultra violet light irradiation.
