By the development of clean and renewable energy source and the fight environmental pollution, The use of photocatalysts has become particulary important. Photocatalysts are used in field such as photocatalytic water splitting, gas sensors, water and wastewater treatment and photocathodic protection. In this thesis, Fe-TiO 2 and TiO 2 nanotubes are prepared by electrochemical anodizing method, then the Ag and Ag-Cu particles were coated with electrodeposition and photodeposition method on the surface of the nanotubes. Their morphology, structure and optical properties were investigated via using FE-SEM, XRD and UV-Visible. To evaluate the photoelectrochemical properties of nanotubes, linear sweep voltametery, open circuit potential test and chronoamprometery were used. All the coated samples are compared to bare samples, showed higher photocurrent density. Also, the application of photodanes for the photocathodic protection of 304 stainless steel was investigated. results showed that the coating improve the properties of photoanodes, so that in the first part, the presence of iron in the structure of the nanotubes reduced the bond gaps. In the first section t 6 (6 minute electrodeposition time) sample with the highest current density, the most negative corrosion potential and the maximum potential drop in open circuit potential test was selected as the optimum sample. In the second part, the results showed that silver and copper metals were present at the surface of the nanotubes, however, no synergistic effect was observed. In this group, the C 2 sample )a specimen sample coated only with copper( with the highest current density, the highest potential drop in open circuit potential test and the most negative corrosion potential was selected as the optimum sample.
