Synthesis and Characterization of Eu-Doped SrTiO3 Photocatalytic Materials Using in the Cathodic Protection of 304 Stainless Steel

In this paper, sample of Eu-doped SrTiO3 was synthesized using hydrothermal method, in which the Eu (NO3)3 and Sr (OH)2 were as the Eu and Sr source. X-ray diffraction (XRD), scanning electron microscope (SEM) were used to characterize the structure and ingredient of the as-prepared samples. The results show that high-purity of SrTiO3 was prepared and structure of SrTiO3 without change with Eu doping. Also, performance of cathodic protection of stainless steel was tested in the photoelectricity cell. Furthermore, the mechanism of the improvement by the rare earth was also detected.
