Ultrathin Anatase TiO2 Nanosheets for High-Performance Photocatalytic Hydrogen Production
1State Key Laboratory of Silicon Materials, School of Materials Science and Engineering, Cyrus Tang Center for Sensor Materials and Application, Zhejiang University, Hangzhou, 310027, China.
Abstract:
An ethanol solvothermal route has been developed to prepare ultrathin anatase TiO2 nanosheets 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 TiO2 nanosheet, 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 H2 evolution rate as high as 17.86 mmol h-1 g-1 , and the corresponding apparent quantum efficiency has been determined to be 34.2%.
