| Abstract: | A novel support of glass spring was developed, and the TiO 2 immobilized photocatalyst was prepared by using dipcoating method. The effect of different preparation conditions on the photocatalytic activity of TiO 2/glass spring catalyst was studied. The results showed that the photocatalytic activity of TiO 2/glass spring was the highest when the slurry concentration of P25 TiO 2 was 0.5%, the times of dip coating was five, and the heat treatment was earried out at 400°C for three hours. The TiO 2/glass spring has the advantage of high illuminated surface area, good mass transfer, low pressure drop, uniform light distribution, minimal transport resistance, and high depth of penetration of UV light. |
