Photocatalysts are catalysts produced by separate electron-hole in present light illumination. Photo catalysts have extended application in many field such as photocatalytic water splitting and photo cathodic protection of 403 stainless steel (403SS) that protect of SS from corrosion in solution. Hematite nanotubes were first prepared by electrochemical anodizing, In the first part, using a chemical bath deposition method at different times, coating of tungsten particles was created on the surface of hematite nanotubes, and in the second part, using silar method in different cycles, nickel sulfide was deposited at different levels on the surface of the nanotubes. Using FE-SEM, XRD, EDX and UV-Visible methods, morphology, structure and optical properties of the resulting samples were investigated. To investigate the photoelectrochemical properties of the samples, voltammetric methods of linear sweep voltametery, chronoamperometric and open circuit potential test were used which all the coated samples had better performance than uncoated samples; In both sections, 403SS is protected photoanodes in present light and in the corrosion solution. As in the first part, the sample of T3 (chemical bath deposition time of three hours) produced a 160 ?A/cm 2 optical current density and a potential drop of -362 mV, and in the second part of the C5 sample (five silar cycle), produced a optical current density of 150 ?A/cm 2 and a potential drop of -425mV were selected as the best sample due to better responsiveness to the tests.
