摘要：
Optimization of multijunction photoelectric conversion materials with a much negative band potential is very important for improving the photoelectric conversion and photoelectrochemical cathodic protection performance because the well-matched multijunction can assist the fast transport of photogenerated electrons. In this paper, a "green" AgInSe2/In2Se3 sensitized TiO2 nanosheet array (NSA) photoanode was prepared. Vertically grown two-dimensional TiO2 NSA with the multijunction of TiO2 NSA/AgInSe2(7)/In2Se3(3) improves the separation efficiency and the transfer of photoinduced charge carriers compared with single AgInSe2 sensitized TiO2 NSA. The TiO2 NSA/AgInSe2/In2Se3 photoanode achieves highly efficient photoelectrochemical cathodic protection performance for 316LSS in NaCl solution under AM1.5 light illumination.
