There is an increasing need for simple and reliable procedure for characterization of photocatalytic activities of developed materials. The aim of work was to develop a method for the determination of quantum yields of supported photocatalysts by employing an aqueous solution of a coumarin. Coumarin is oxidized in the presence of irradiated TiO2 to 7-hydroxycoumarin, which could be fluorimetrically detected at low concentrations. Additionally, also a newly defined parameter, so called mass efficiency, was introduced as an advantageous way of defining the photocatalytic activities.
