The influence of ethanol on photocatalytic destruction of dyes (methylene blue, safranine, eosine, phenosafranine) in the presence of TiO2 powders and CdS nanoparticles in aqueous solutions was investigated. Anatase showed higher activity in water-ethanol solutions compared to rutile. The most active nanoparticles were CdS and CdS partially substituted by indium. It was established that ethanol increases the rate of photocatalytic destruction if it does not compete with the substrate for sorption centers on the photocatalyst surface.
