Large-scale, ultrathin and (001) facet exposed TiO2 nanosheet superstructures and their applications in photocatalysis†
Abstract
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 μm, while the thickness of the nanosheets was only about 2–4 nm. The anatase TiO2 nanosheet superstructures have superior photocatalytic performance.
