Ak. Lavrentieva, 5,Novosibirsk, 630090, RussiaPhotocatalysis on semiconductors is a good method of air and water purificationfrom organic admixtures wich has been extensively developed over last decades [1].Main efforts are focusing on the synthesis of highly active photocatalysts which areusually based on the anatase form TiO 2. At the same time adsorption properties ofthe photocatalytic system also influence on the rate of photocatalytic processesespecially in the low concentration range which is obvious from the classicLangmuir–Hinshelwood (L.–H.) dependence of the product formation rate on the gasconcentration of a substrate:k⋅K⋅AdP ads= ⎯⎯⎯⎯→dP ≈ k⋅K Kads⋅Adtads ⋅ A
