| 英文摘要 | In order to develop novel anti-corrosion technologies of metals, the photoelectrochemical cathodic protection (PECCP) coating with zinc indium sulfide/titanium oxide (Zn2In2S5/TiO2) was successfully fabricated and its enhanced anticorrosion mechanism was explored in marine environment under light and dark condition, respectively. It found that the improvement of anticorrosion performance is due to the introduction of Zn2In2S5/ TiO2 with Z-scheme heterojunctions, which has been verified systematically through theoretical calculations and electrochemical experiments. Under illumination, the photoelectrons generated by Zn2In2S5/TiO2 Z-scheme heterojunctions were accumulated on the conduction band (CB) of Zn2In2S5 at an internal electric field (IEF) pointing from Zn2In2S5 to TiO2, which endowed Zn2In2S5/TiO2 with strong oxidation-reduction ability to provide PECCP for Q235CS and 304SS in 3.5 wt% NaCl. In the dark state, Zn2In2S5/TiO2 Z-scheme heterojunctions served as nanofills to enhance the maze effect, ensuring the remarkable anticorrosion performance of PECCP coating. Furthermore, the protective effect of Zn2In2S5/TiO2 coating was quantified as 74.23 % and 98.91 % for 304SS and Q235CS in 3.5 wt% NaCl for 30 days, respectively. |
