Large-scale, ultrathin and (001) facet exposed TiO2 nanosheet superstructures and their applications in photocatalysis

Large-scale, ultrathin, and (001) facet exposed anatase TiO2 nanosheet superstructures were synthesized by a facile one-step solvothermal method. The length and width of the nanosheets was as high as 1.5-2 mu m, while the thickness of the nanosheets was only about 2-4 nm. The anatase TiO2 nanosheet superstructures have superior photocatalytic performance.
