Porous TiO2 film was prepared by sol-gel method from TiO2 sol containing polyvinylpyrolidone (PVP). Photocatalytic activity of the film was evaluated by the elimination rate of ethylene. Several adsorbents including zeolite and silica powders were incorporated into the TiO2 film. All the adsorbents enhanced the activity. The optimum adsorbent content was 0.005-0.01 g/ml of the coating sol solution. Silica provided better activity than zeolite. At high humidity and in dry air the activity decreased.
采用溶胶-凝胶法，以含聚乙烯吡咯烷酮（PVP）的TiO₂溶胶制备了多孔TiO₂薄膜。通过乙烯的去除率评估该薄膜的光催化活性。将包括沸石和二氧化硅粉末在内的几种吸附剂掺入TiO₂薄膜中。所有吸附剂均提高了活性。最佳吸附剂含量为涂层溶胶溶液的0.005 - 0.01 g/ml。二氧化硅比沸石具有更好的活性。在高湿度和干燥空气中，活性会降低。
