摘要：

Bismuth selenide (Bi2Se3) was chosen as the sensitizer to TiO2 nanorod (NR) arrays photoelectrode to harvest infrared (IR) light for its narrow band gap. For utilizing more amount of IR solar energy, Bi2Se3 nanoparticles (NPs) were grown up to a relative larger grain size. And, a cadmium sulfide (CdS) NPs intermediate layer was introduced to help, to coordinate, the structure of band-edge levels in Bi2Se3/CdS/TiO2 electrode. Here, a chemical vapor deposition (CVD) strategy was introduced to assemble this kind of composite photoelectrode. And a cascade structure of band-edge levels constructed in it when achieving electrostatic equilibrium in Na2S/Na2SO3 aqueous solution electrolyte revealed by electrochemical analysis method, which will facilitate the hydrogen generation.
