eng	EFFECT OF THE TYPE OF PHOTOCATALYST ON THE EFFICIENCY OF PHOTOCATALYTIC DEGRADATION	Photocatalysis is a reaction that occurs in the presence of a semiconductor and light [1]. The semiconductor is also a catalyst that accelerates the reaction and is often a metal oxide, most often TiO2 [2]. Photocatalysis is one of the Advanced Oxidation Processes (AOP), which utilize the high reactivity of hydroxyl radicals (·OH), which makes them effective in degrading a wide range of contaminants. Another great advantage of AOP is that they occur under normal conditions (especially pressure and temperature), which facilitates their application. The aim of the work was to evaluate the efficiency of dimethyl sulfoxide and methylene blue degradation using four types of TiO2-based photocatalysts (P25, AV01, PRETIOX CG100 and UV100) under various experimental conditions. The effect of the photocatalyst concentration, the intensity of the radiation, etc. were observed. It was found that of the tested photocatalysts, P25 and AV01 were the most effective, while PRETIOX CG100 was evaluated as the least suitable for applications in aqueous environments.
