Study on the effect of TiO2/MgIn2S4 Heterojunction Photoelectrode on the Photoe-lectrochemical Cathodic Protection Performance of 316L Stainless Steel
In this paper,TiO2 nanosheets photoelectrodes was firstly prepared by hydrothermal method,MgIn2S4 nanoflowers were prepared by secondary hydrothermal on TiO2 nanosheets,and a series of TiO2/MgIn2S4-X heterojunction photoelectrodes were prepared by controlling the temperature of the hydrothermal reaction of MgIn2S4.The performance of the heterojunction photoelectrodes on the photoelectrochemical cathodic protection of 316L stainless steel was investigated.The experimental results show that the photoelectrochemical cathodic protection performance of TiO2/MgIn2S4-X heterojunction on 316L stainless steel increases with the increase of the hydrothermal temperature,and the photoelectrochemical cathodic protection performance of TiO2/MgIn2S4-200 is the best when the hydrothermal temperature is 200℃.
