采用造纸技术制备复合二氧化钛 (TiO2)-沸石片，并测试其去除乙醛的能力，乙醛通常用作典型的挥发性有机化合物。结果表明，复合 TiO2-沸石片在紫外线照射下比单独的 TiO2 片能更有效地去除乙醛。在本工作采用的条件下，通过TiO 2 /沸石比为1:4的复合TiO 2 -沸石片去除乙醛特别有效，尽管该复合片仅包含TiO 2 片中TiO 2 量的五分之一。此外，TiO2和沸石的组合是解决吸附剂的缺点的有效方法，即当材料饱和或与吸附物平衡时性能下降。因此，复合TiO 2 -沸石片可用作防止环境污染的高功能材料。 (C) 2002 年 Kluwer 学术出版社。
Composite titanium dioxide (TiO2)-zeolite sheets were prepared using a papermaking technique and were tested with regard to their ability to remove acetaldehyde, which is often used as a typical volatile organic compound. It was demonstrated that the composite TiO2-zeolite sheet could remove acetaldehyde much more effectively under UV irradiation than a sheet of TiO2 alone. Acetaldehyde removal by a composite TiO2-zeolite sheet with a TiO2/zeolite ratio of 1 : 4 was particularly effective under the conditions adopted in this work although the composite sheet contained only one fifth of the amount of TiO2 in the TiO2 sheet. Additionally, the combination of TiO2 and zeolite was a useful method to solve the disadvantage of adsorbents, which were the decrease of the performance when the material was saturated or equilibrated with the adsorbates. Consequently, a composite TiO2-zeolite sheet can be utilized as a high functional material to prevent environmental pollution. (C) 2002 Kluwer Academic Publishers.
