摘要
Single crystal TiO_2 nanosheet array films with dominant {001} Facets were synthesized on FTO by a hydrothermal method. A simple strategy for the selective deposition of Cd S nanoparticles on the low energy {101} facets by controlling F content on the surface of Ti O2 nanosheets is developed. For CdS/TiO_2, under light irradiation, the photo-generated electrons flow from {001} to {101} facets,meanwhile, the photo-generated electrons transfer from Cd S nanoparticles to the TiO_2 nanosheets. The deposition of Cd S nanoparticles on the {101} facets will shorten the path-ways that electron must travel. Herein, the synergistic effect of selective deposition of Cd S nanoparticles on the {101} facets of Ti O2 nanosheets combined with the different band edge positions of {001} and {101} facets, which would facilitate the spatial separation of electrons and holes on different facets, leading to enhanced photoelectronic performance.
