Synthesis of Flower-Shaped Ag@TiO2 Core-Shell Nanoparticles and Their Photocatalytic Properties |
| 초록 |
Flower-shaped core-shell Ag@TiO2 nanoparticles have been synthesized by a hydrothermal route. The morphological and structural features were characterized using transmission electron microscopy (TEM), X-ray powder diffraction (XRD), and UV-vis spectroscopy, and so on. It was revealed that the flower-shaped TiO2 shells process anatase-typed crystallinity and well-defined interface continuity within Ag-TiO2 heterointerface. The photocatalytic properties of the as-prepared nanostructured core-shell Ag@TiO2 nanoparticles were investigated by photo-initiated oxidation degradation of gaseous acetaldehyde. It has been indicated that the nanostructured core-shell Ag@TiO2 photocatalyst represents high catalytic activities when exposed to UV or visible light irradiation. Finally, the structure-property relationship of as-synthesized nanostructured core-shell Ag@TiO2 nanoparticles was discussed. |
