Název v původním jazyce

Photocatalytic properties of different TiO(2) thin films of various porosity and titania loading

Popis výsledku v původním jazyce

Thin sol-gel titania films with varying porosity but constant mass were coated on SiO(2)/glass substrate. The mass was kept constant by changing the withdrawal rate of dipping from a titania sol. The porosity properties of the films were determined by the analysis of adsorption isotherms of Kr at ca 77 K. Photocatalytic performance of TiO(2) layers in the degradation of Acid orange 7 (AO7) and 4-chlorophenol (4CP) in aqueous solution depends on the mass of titania but not on the porosity/surface area ofthe films. On the contrary, in the degradation of thin layers of Resazurin (Rz) ink and methyl stearate (MS) deposited on the TiO(2) film surface, the activity of the films is clearly enhanced due to the porosity but does not depend on titania mass itself. Obtained data suggest that while in an aqueous solution the reaction rate depends primarily on the mass of titania and amount of absorbed light, in solid thin films test the porosity/surface area together with interfacial area of test
