| 英文摘要 | Chromium oxide nanotubes were successfully prepared using multi-walled carbon nanotubes (MWCNTs) as a template via a supercritical fluid-mediated route. In this method, with chromium (III) nitrate nonahydrate as precursor, chromium oxide was first deposited on MWCNTs in supercritical ethanol in the presence of NH(4)HCO(3). The as-prepared chromium oxide/MWCNT nanocomposites were characterized by transmission electron microscopy, x-ray diffraction, infrared spectroscopy and thermogravimetric analysis. It was demonstrated that the MWCNTs were coated with a layer of amorphous Cr(2)O(3)center dot xH(2)O. The thickness of the Cr(2)O(3)center dot xH(2)O sheath on MWCNTs could be tuned by manipulating the ratio of precursor to MWCNTs. Calcining the composites at 550 degrees C, the MWCNTs were removed, producing polycrystalline alpha-Cr(2)O(3) nanotubes. The as-prepared alpha-Cr(2)O(3) sample was used as a sensor material to detect ethanol vapor, and it was demonstrated that the alpha-Cr(2)O(3) nanotubes exhibited good performance even at 400 degrees C. |
