| 英文摘要 | Flower-shaped core-shell Pt@TiO2 nanoparticles have been synthesized successfully by a simple hydrothermal route using TiF4 as precursor. Morphology of the product was investigated by transmission electron microscopy (TEM), selected area electron diffraction (SAED) and X-ray diffraction technique. It has been revealed that the TiO2 shells of core-shell Pt@TiO2 nanoparticles are constructed by multiple wedge-shaped petals of TiO2 crystals with anatase-type crystalline phase. The SAED pattern of TiO2 shells reflecting the formation of wedge-shaped TiO2 petals is because of the preferential growth of (004) crystal planes surrounded by (101) facets of TiO2 crystal planes. The high phototocatalytic performance of flower-shaped core-shell Pt@TiO2 nanoparticles is also largely attributed to the high Schottky energical barrier within PtTiO2 hetero-interface and the interaction between synchronously vibrated electrons within Pt and electrons in valence band of TiO2 crystals.
