In this thesis, by electrochemical anodizing of WO3-TiO2 nanotubes, the coating of copper oxide and iron oxide in various concentrations by coating with a chemical bath (CBD) coating on WO3-TiO2 nanotubes. The morphology, structure, optical properties of the sample prepared by FE-SEM, XRD, EDX, UV-Vis and Raman spectroscopy were investigated. In these studies, the formation of nanotubes, the presence of tungsten, iron and copper in nanotubes and the reduced of energy gaps, photocatalysts have been proven. Electrochemical impedance spectroscopy of the photo anodes showed that the electron transfer resistivity in the modified nanotubes with iron and copper has compared to the unmodified WO 3 -TiO 2 nanotubes. LSV and CA and OCP tests were used in which all specimens exhibited higher flows than the non-coated sample, so that the highest flow is related to the WT4 sample, which is higher than the unopposed WO3-TiO2 sample. The stability of the samples was studied using chronoamperometric test and it was shown that photocatalysts are very stable under long exposure.Finally, the production of hydrogen gas was studied. The highest amount of hydrogen production is 90 ?l per hour. In general, the results of the studies showed that the photovoltaic properties of nanotubes were improved due to the coating of the metals, so that the sample WT 4 (0.025 molar of copper and 0.075 molar of iron) was better due to better response to the tests. It was chosen as an optimal sample.
