Large-scale synthesis of metastable TiO2(B) nanosheets with atomic thickness and their photocatalytic properties.

A one-pot method was developed to prepare atomic thick nanosheets of metastable TiO(2)(B), which has a unique open structure owing to the coupling of intrinsic channels and the preferentially exposed (010) facets. They display high activity of doping due to the rapid incorporation and diffusion along these open channels.
