  • Title: Improved photocatalytic activity of zeolite- and silica-incorporated TiO2 film.
    Author: Tanaka K, Fukuyoshi J, Segawa H, Yoshida K.
    Journal: J Hazard Mater; 2006 Sep 21; 137(2):947-51. PubMed ID: 16704899.
    Abstract:
    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.
