A low-dimensional ZnO film was fabricated on 316L stainless steel (SS) surface by hydrothermal method. Scanning electron microscopy (SEM) showed that the film was consisted of microrods with diameter of about 0.6 μm. X-ray diffraction (XRD) proved the hexagonal phase ZnO of the film. The photoelectrochemical behavior of the microrod ZnO coated electrode was investigated in the presence and absence of UV light irradiation by the open circuit potential (OCP), photocurrent, polarization curve and

The photogenerated current provided noticeable cathodic protection on 316L SS under UV light irradiation. The mechanism of photocurrent cathode protection was discussed.
