The Bi2S3-modified ZnO nanowires (Bi2S3/ZnO) were prepared by the electrochemistry deposition and successive ionic layer adsorption and reaction and their photoelectrochemical cathodic protection performance was explored. Compared with that of pristine ZnO, the photo-response of the Bi2S3/ZnO heterostructure thin-film red shifted to the visible light range and their photocathodic protection for 304 stainless steel and Q235 carbon steel was improved under visible light. Furthermore, the enhanced mechanism was investigated systematically explored and it found that the appropriate energy level arrangement and the construction of heterojunction is responsible for the enhanced photocathodic protection performance.

Bi2S3 纳米颗粒/ZnO 纳米线异质结薄膜用于改进可见光下 304 SS 的光电化学阴极保护
采用电化学沉积和连续离子层吸附反应制备Bi 2 S 3修饰的ZnO纳米线（Bi 2 S 3 /ZnO），并对其光电化学阴极保护性能进行了研究。与原始 ZnO 相比，Bi 2 S 3的光响应/ZnO异质结构薄膜红移至可见光范围，可见光下对304不锈钢和Q235碳钢的光阴极保护得到改善。此外，系统地研究了增强机制，发现适当的能级排列和异质结的构造是增强光阴极保护性能的原因。
