Abstract: The TiO 2 photocatalysts loaded on the novel carrier of glass spring with the immerse coating technique were developed. The light distribution in different packing bed show that the distance through which light travels in the photocatalyst bed of glass spring carrier is 8 times and 28 times longer than that of glass ball and of 0.5% P25 slurry respectively. The TiO 2 photocatalyst film is more even with lower concentration TiO 2 slurry for several times immerse coating, and behaves higher photocatalytic activity. The novel loaded photocatalyst has such advantages as high ratio of illuminated surface areas to the reactor volume and well distributed light throughout the packed bed.
