"Layers prepared from TiO2 powder particles effectively combine two crucial parameters of heterogeneous photocatalysis, namely high surface area and immobilization of the photocatalyst. Sedimentation or spraying of the powder suspension are the most common procedures to prepare such layers. Other possible techniques are electrophoresis and dip-coating. The type of powder photocatalyst as well as the way of layer deposition could significantly affect the properties of the formed particulate films. Therefore the present study deals with the preparation of particulate TiO2 layers. Three various powder photocatalysts, namely P25 (Degussa) and anatase Tit 1 and Tit 2 of a Czech production, were used and three different techniques, i.e., spraying, electrophoresis and dip-coating, were applied. The prepared films were characterized by SEM, XRD and BET methods. The photoactivity of layers was tested through photocatalytic degradation of a model organic compound Acid Orange 7 (2-hydroxy-1-naphtylazo benzensul"@en . "RIV/60461373:22310/07:00018688" . .
