Co-Ce codoped TiO2/SiO2/NiFe2O4 magnetic mesoporous microspheres material were prepared by sol-gel process with tetrabutyl titanate as raw materials，Co and Ce as doping ions, PS-SiO2/NiFe2O4 particles as the cores, sodium dodecyl sulfate and polyvinylpyrrolidone as templates.
Introduction TiO2 is a kind of semiconductor materials with high activity, chemical stability, harmless and recyclable.
Under UV irradiation, the charge transitions appear on the surface of the mesoporous materials, and outside additional electric fields generate relative to bulk materials.
