CuInS2/TiO2 heterojunction with elevated photo-electrochemical performance for cathodic protection
文献摘要：
Semiconductor quantum dots with high quantum yield and photovoltaic conversion efficiency have ush-ered in a brilliant moment for constructing internal electric field heterojunctions for photogenerated ca-thodic protection applications.In this paper,TiO2 nanotubes 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 CuInS2 quantum dots.Compared with pure TiO2 photoelectrodes,the modification improves sunlight absorption efficiency and provides photoelectron cathodic protection to the 304 stainless steel(304 SS).Through 9 h solvothermal reaction,the CuInS2/TiO2 coupled with pro-tected 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 CuInS2 and TiO2 established a p-n heterojunction with well-matched energy level,which can effectively facilitate the carrier separation and retain the strong redox capbility of photo-induced electrons and holes.
