A photoelectrochemical method on metal preservation is disclosed that includes applying a coating on metal surface and curing the coating. The coating includes: A) the film-forming component; and B) the surface modified nanometer titanium dioxide, which consists of nanometer titanium dioxide particle as substrate and the nonionic surfactant covered on the substrate surface. The diameter of the nanometer titanium dioxide substrate is 1-100 nm. The hydrophile-lipophile balance value of the nonionic surfactant is 1-10 and is contained of 1-20 wt % based on the weight of nanometer titanium dioxide substrate. The content of the surface modified nanometer titanium dioxide is 0.1-10 wt % based on the total weight of the coating. The photoelectrochemical method on metal preservation through this disclosure is low cost and high efficient and obviously reduce the corrosion speed.
