Preparation and properties of photocatalytic composites based on titanium(IV), copper(II), and sodium(I) oxides

We have established conditions for the preparation of multiphase composites based on titanium(IV) and copper(II) oxides in a wide composition range and examined correlations between the phase composition, texture, and preparation conditions of the composites. Some of them have a mesoporous structure, consist of nanoparticles, and exhibit photocatalytic activity under illumination in the visible range.
