Dependencies of photocatalytic activity (PA), adsorption spectra, electroconductivity (σ), and catalytic activity (CA) on quantitative and phase composition of Zr4+- and Ti4+-containing oxides were determined. It was found, that PA and CA linearly depend on ? and the interrelation between these efficiency parame- ters of chemical reaction was ascertained.

Key word photocatalytic activity, catalytic activity, zirconium dioxide, doping by titanium.
