Zeolite powder was incorporated into the TiO2 film. 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 TiO2 film. 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.
将沸石粉末掺入二氧化钛薄膜中。对它们在气相中降解苯的光活性进行了评估。本研究使用了七种沸石样品，每种都增强了光催化降解效果。气体样品中的湿度增加了降解，但抑制了苯在二氧化钛薄膜上的吸附。值得注意的是，光活性与沸石的硅铝比成反比，而吸附量则随该比例增加。有人认为，沸石对水的吸附有助于提高苯的降解率。
