英文摘要：

Well-aligned open-ended multi-walled carbon nanotube （MWCNT） arrays were prepared via chemical vapor deposition （CVD） method in porous anodic aluminum oxide （AAO） templates without depositing any transition metals as catalyst. Effects of the CVD temperature and heat treatment were studied in detail. Well-aligned open-ended MWCNT arrays were obtained at the CVD temperature above 600℃; when CVD temperature is reduced to around 550℃, CNTs, CNFs and other structures existed at the same time; no CNTs or carbon nanofibres （CNFs） could be fouad as the CVD temperature is below 500℃, and only amorphous carbon in the porous AAO template was found. Experimental results showed that the AAO template is catalytic during the CVD process, and it has the following two effects： to catalyze thermal decomposition of acetylene and to catalyze conversion of carbon decomposed from acetylene into CNTs or CNFs. Heat treatment could improve the graphitization degree, but it might also introduce new defects.
