| 英文摘要 | The purification of swcnt by oxygen oxidation in licl-kcl molten salt was investigated. 5 g of as-prepared swcnt was suspended in 200 g of molten salt (w(licl) : w(kcl) = 55 : 45) at 470 degrees c by agitation. after 2 h oxidation in 300 ml.min(-1) oxygen flow, 3.8% of purified swcnt was obtained. the oxidation degree could be controlled by adjusting the reaction temperature and oxygen flow rate. scanning electron microscopy (sem), transmission electron microscopy (tem), thermogravimetric analysis (tga) and raman spectra were employed to characterize the as-prepared and purified swcnt. the results indicated that almost all of the amorphous carbon in as-prepared swcnt was removed. however, the swcnt can survive from this purification process. |
