Novel semiconductive materials containing TiO2 dispersion, doped with zinc and additional modifying salts of Cu2+, Fe2+, and Co2+, have been obtained. Such materials can be used as effective catalysts in the Cu2+ reduction. Exposition to UV-light followed by the dark storage leads to complex changes of the catalytic activity of TiO2products. Detailed character of the changes depends on the presence of a doping agent and on the nature of modifying salts' anion. The scheme of the electron transfer processes has been proposed to describe changes of the activity.
