将沸石粉掺入到TiO2薄膜中。以苯为目标物，考察了它们的气相光催化降解性能.七个沸石样品用于本研究中，每一个都增强了光催化降解。气体样品中的湿度增加了降解，但抑制了苯的吸附到TiO2膜。结果表明，沸石的光活性与硅铝比成反比，而吸附量随硅铝比的增加而增加。结果表明，沸石分子筛对水的吸附有助于苯的降解。
Zeolite powder was incorporated into the TiO2film. Their photoactivities were evaluated for the gas phase degradation of benzene. Seven zeolite samples were used in this study and each enhanced the photocatalytic degradation. Humidity in the gas sample increased the degradation, but suppressed the adsorption of benzene to the TiO2film. It was noted that the photoactivity was inversely proportional to the silica/alumina ratio of zeolite, whereas adsorption increased with this ratio. It was suggested that the adsorption of water onto zeolite contributes to the enhancement of benzene degradation.
