Abstract

The kinetics of photocatalytic oxidation of ethanol vapors under visible light (λ> 420 nm) on the TiO2 modified with noble metal (Au and Ag) and ions (Pt, Pd and Ru) is studied. The effect of the modificator on the activity of Au/TiO2 and Pt/TiO2 photocatalysts is studied. The optimum metal content is ~1 wt.%. The quantum efficiency is calculated for all the samples. The photocatalytic activity of the studied samples is compared with activity of the commercial sample of Kronos vlp7000. The dependence of Ag/TiO2 catalytic activity on the silver ion reduction method is shown.
