摘要
通过控制水热反应过程中的钛酸四丁酯的浓度,有效调控了TiO2光电极的形貌,同时研究了形貌对316L不锈钢的光电化学阴极保护性能的影响.实验结果表明,钛酸四丁酯的加入量为1.25mL时,TiO2-2具有最大的光致电位降和光致电流密度,表明其对316L不锈钢具有最优的光电化学阴极保护性,电化学阻抗谱的结果表明,载流子的迁移能力的提升是其光电化学阴极保护性能提升的主要原因.
Abstract
The micromorphology of TiO2 photoelectrod was effectively regulated by controlling the concentration of tetrabutyl titanate during the hydrothermal reaction process,and the effect of morphology on the photoelectrochemical cathodic protection performance of 316L stainless steel was also investigated.The experimental results show that TiO2-2 has the maximum photoinduced potential drop and photoinduced current density when the addition amount of tetrabutyl titanate is 1.25mL,indicating that it has the optimal photoelectrochemical cathodic protection property for 316L stainless steel,and the results of electrochemical impedance spectra indicate that the enhancement of the carrier mobility is the main reason for the increase of its photoelectrochemical cathodic protection performance.
