title: Ultrathin Anatase TiO2Nanosheets for High-Performance Photocatalytic Hydrogen Production.
abstract: An ethanol solvothermal route has been developed to prepare ultrathin anatase TiO2nanosheets with dominant {001} facets (≈97%), a thickness of ≈2.5 nm, and a side length of ≈200 nm. The introduction of ethanol solvent significantly enhances the content of surface chemisorbed F-on the TiO2nanosheet, which has a higher stability and further lowers the surface energy of {001} facets, giving rise to the large percentage of active {001} facets. Adopting well-defined morphology, such nanosheets loaded with 1 wt% Pt exhibit an H2evolution rate as high as 17.86 mmol h-1g-1, and the corresponding apparent quantum efficiency has been determined to be 34.2%.
