| 英文摘要 | Semiconductor quantum dots with high quantum yield and photovoltaic conversion efficiency have ushered in a brilliant moment for constructing internal electric field heterojunctions for photogenerated cathodic protection applications. In this paper, TiO_2nanotubes grown vertically on the surface of titanium substrates were modified via a combination of conventional electrochemical oxidation and a one-step solvothermal pathway to sensitize with CuInS_2quantum dots. Compared with pure TiO_2photoelectrodes,the modification improves sunlight absorption efficiency and provides photoelectron cathodic protection to the 304 stainless steel(304 SS). Through 9 h solvothermal reaction, the CuInS_2/TiO_2coupled with protected 304 SS exhibited an excellent property when the simulated sunlight irradiation. Its mixed open circuit potential is negatively shifted to-0.99 V, at the mean time with a stable photocurrent density(118 μA cm~(-2)). The results indicate that CuInS_2and TiO_2established a p-n heterojunction with wellmatched energy level, which can effectively facilitate the carrier separation and retain the strong redox capbility of photo-induced electrons and holes. |
