Abstract

The electrical conductivity, magnetic susceptibility, and catalytic activity (photoreduction of Methylene Blue to a leuco form and reduction of metal ions) of TiO2–Bi2O3 materials were studied. Their catalytic activity was shown to be determined by their phase composition and structural perfection. The observed correlations between the properties studied are interpreted in terms of active sites for catalytic reactions.
