- Аннотация: Over the past decades, titania has been the object of close attention of scientists all over the world. Titania is a wide-gap semiconductor with a band gap varying from 3.2 to 3.4 eV, and continuous illumination by UV radiation must be used for reactive electrons and holes generation. The way to improve the photocatalytic characteristics of titania is doping with ions of metals or nonmetals and to prolong the lifetime of photoexcited carriers (electrons and holes) by their spatial separation in nanoheterostructures, thus prevent recom-bination. In this work we have obtained nanoheterostructures effectively absorbing light in the visible spectral region and accumulating photoexcited charge carriers, providing rather long catalytic activity of the produced structures after illumination is turned off. At the same time we have seriously checked out the behavior of the used nanoheterostructures after adsorbtion of organic dye molecules on their surface. Organic dye molecules adsorption is involved in a standard method for the photocatalytic activity measurements.
