In this work, we developed a fluorine-assisted hydrothermal strategy to in-situ decorate TiO2 quantum dots on anatase nanosheet. The prolonged hydrothermal time and subsequent defect healing are the keys to fabricate this structure. The dots show obvious quantum-size effect with local band structure matching the {001} surface of nanosheet very well. In this way, a shorter and more effective charge separation channel is introduced between the quantum-dots and nanosheet, which promotes the photocatalytic activity for 3.4-fold. To our knowledge, this is the first report on the anatase nanosheet decorated with TiO2 quantum dots. This work suggests that engineering the local surface structure may be an effective way for highly active photocatalyst.
