For TiO2 nanostructure preparation microwave assisted [1], anodization [2] and PEO [3] methods where used. Nanofibers, nanotubes and nanopores coatings were obtained respectively. As-prepared nanostructures were modified with Pt, Au and Ag nanoparticles by using chemical deposition method and calcination at 500oC for 2 h. Samples containing 0.1, 0.5, and 1wt% of dopant on each morphology of TiO2 substrate were prepared. Modified TiO2 photocatalysts are with up to 50% higher activity with respect to pure TiO2 anatase powder. Catalysts modificated with Au had higher activity with respect to that ofmodificated with Pt and Ag. Catalysts with nanofiber morphology are with up to 3x higher photocatalytical activity.
