Abstract Heterojunction engineering, as a rising star in the photoelectrochemical cathodic protection (PECCP) field, contributes to promote the separation of the photoinduced electrons and holes. In this paper, the TiO2/MgTixOy multiphase-heterojunction film was prepared and its PECCP performance was studied. Due to a good energy band alignment gradient formed between the multiphases, the separation efficiency of the photoinduced electrons and holes generated by TiO2/MgTixOy are dramatically enhanced, leading to its good PECCP performance and high stability. SKP is, for the first time, used to study the surface work function of the TiO2/MgTixOy multiphase-heterojunction film for characterizing its PECCP performance.

一种新型的 TiO2 纳米管阵列/MgTixOy 多相异质结薄膜,具有高效的光电化学阴极保护

摘要 异质结工程作为光电化学阴极保护(PECCP)领域的一颗冉冉升起的新星,有助于促进光生电子和空穴的分离。本文制备了TiO2/MgTixOy多相异质结薄膜并对其PECCP性能进行了研究。由于多相之间形成了良好的能带排列梯度,TiO2/MgTixOy产生的光生电子和空穴的分离效率显着提高,从而使其具有良好的PECCP性能和高稳定性。SKP 首次用于研究 TiO2/MgTixOy 多相异质结薄膜的表面功函数,以表征其 PECCP 性能。
