Abstract :
Composite photocatalyst of Glass-Microspheres/TiO2 was successfully synthesized by sol-gel method using tetrabutyl titanate as raw materials and hollow Glass-Microspheres as the carrier. The samples were characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM). It was present that a uniform film of anatase TiO2 was formed on the surface of GMS.In addition, The experiment of photocatalytic degradation of organophosphorus solution indicated that photocatalytic activity of Glass-Microspheres/TiO2 was higher than that of P25 and the decomposition efficiency keep up to 75% after five times.
