چکیده انگلیسی
Hollow silica nanostructures exhibit important applications in catalysis, sensing, and gene delivery due to their increased surface areas, good biocompatibility, and unique optical features. Here we report a simple and green approach to synthesize silica nanotubes using environment-friendly ZnO nanorods as templates. The ZnO nanorods are first coated with a layer of uniform silica shell by a sol-gel method. Then silica nanotubes are derived from the ZnO@SiO2 nanohybrids after removal of the ZnO nanorod cores in diluted hydrochloric acid solution. The samples at different stages were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, Energy-dispersive X-ray spectroscopy, and Transmission electron microscopy. By controlling the structure of the ZnO@SiO2 nanohybrids, such as shell thickness, and the diameter and length of ZnO nanorods, size controllable SiO2 nanotubes can be expected.
