Photocatalytic Degradation of Reactive Gaudy Red X-3B Dye on Immobilized Nanometer TiO2
Abstract:
The washed and dried porous silica gel was soaked in water glass of moderate viscosity, then mixed with nanometer TiO2, stired until TiO2 has been uniformly distributed on the porous silica gel. After dried naturally, it was calcined at 300℃ for 1h to give the immobilized nanometer TiO2 which was mechanically and chemically stable, and can be reused. Under the illumination of high-pressure Hg lamp, the X-3B dye could be degraded almost quantitatively(98%) in a solution containing the photocatalyst, Fe3+ and H2O2 with bubbling of air.
