【 摘 要 】

I using the sol-gel/immacing jacquard to load TiO2 film on the fiberglass. Through orthogonal test, the photocatalytic performance of the photocatalytic degradation of nitrobenzene wastewater by the loading TiO2 was investigated, including the ratio of glue solution, the calcination temperature, the calcination time and the number of times of coating. The best condition of preparation of glass fiber load titanium dioxide thin film is: ethanol: water: the molar ratio of nitrate 10:6:1, calcination temperature is 450 °C, calcination time is 90 minutes, coating number 4 times. The repeated test results showed that under the optimal preparation conditions, the degradation rate of nitrobenzene with a concentration of 40mg/L was up to 93.4%. The catalyst can be reused. The results of electron microscopy showed that the catalyst on the surface of glass fiber was evenly distributed in a tubular shape. The XRD resulted show that the crystal type of TiO2 supported by glass fiber is sharp-titanium ore type with good photocatalytic performance.
