TiO_2光催化降解酸性蓝染料溶液的研究

利用溶胶-凝胶法在玻璃纤维表面涂覆TiO2在紫外灯管或太阳光的照射下处理染料溶液,使染料分子降解.研究结果表明,采用该方法可以达到较好的降解效果,在溶液中添加Fe3 电子掩蔽剂或在TiO2中掺杂Y2O3,均能显著地促进光催化反应.

Investigation on Degradation of Dye Solution by TiO_2

The surface of glassfiber is coated with TiO2 by sol-gel method. A dye solution is treated under UV lamp or the sunlight,and the dye moleculars are degradeted. The study shows that a good degradation effect is obtained by using this method. The photo catalysis reaction can evidently by enhanced by adding Fe3 in the dye solution or by doping with Y2O3 in TiO2 sol.
