Tartalmi kivonat:Photocatalysis is a research field that offers a variety of environmentally friendly solutions for the degradation of organic pollutants. With this method, the different contaminants can be oxidized to carbon dioxide and water, which are obviously no longer harmful. Among the semiconductors TiO2 is the most studied and used photocatalyst because of its non-toxicity, high photocatalytic performance, chemical inertness, environmentally benign nature and low cost. In the present work copper nanoparticles were deposited on two different commercial TiO2 (Evonik Aeroxide P25 and Aldrich anatase). During the synthesis, the concentration of copper was systematically varied (0.5%, 1.0%, 1.5%, 5.0% and 10.0 wt.%). The morpho-structural properties were investigated using XRD, TEM, EDX and DRS methods. The photocatalytic activity was evaluated under UV-light, using methyl orange as a model- and ketoprofen as a real pollutant.
