摘要

A series of {001} facets dominated TiO ₂ nanosheets with even distributed bulk oxygen vacancies and Ti ³⁺ were synthesized by a simple hydrothermal method at different temperatures. The oxygen vacancy and Ti ³⁺ quantity increased with the hydrothermal temperature from 180°C to 240°C. The existed oxygen vacancies and Ti ³⁺ significantly improve the visible-light photoactivity, which can be assigned to the enhanced visible light adsorption, •OH generation ability and reduced photoelectrons and holes recombination rate.
