摘要：

The Fe3+ and N-doped 3SnO(2)/TiO2 composite thin films and undoped films coated on glass fibers were prepared by sol-gel and dip-coating methods. The films were calcined at 600 degrees C for 2 hour and characterized by XRD, SEM, EDS and XPS. The photocatalytic activity of the coated glass fibers was determined by means of degradation of a methylene blue (MB) solution and humic acid (HA). It was found that the optimized 20N/3SnO(2)/TiO2 composite films exhibit a high photocatalytic activity and HA could be rapidly removed from water. The main factor affecting the HA degradation of 20N/3SnO(2)/TiO2 films is quantity of glass fibers loading, irradiation power of UV lamp and flow rate of water.
