摘要

Carbon nanofibres (CNFs) exhibiting bamboo-like, hollow fibril morphology were prepared from a mixture of polyethylene glycol (PEG) and iron-based compounds such as Fe_2(SO_4)_3 centre dot nH_2O, Fe(NO_3) centre dot 9H_2O or FeO(OH) by a thermal process. These materials were well mixed in distilled water prior to thermal treatment in an airitrogen atmosphere. With increasing temperature, the mixture underwent solvent removal, dehydrogenation, thermal decomposition, carbonization and catalytic graphitization to form CNFs. Results show that CNFs can be formed with different PEG/catalyst ratios (100/1-1000/1 by weight) at 750 deg C. The catalyst effect is discussed for the formation of bamboo-like CNFs. The diameter of the CNFs was about 30-50 nm while the length was a few micrometres.
