Abstract

The carbon nanomaterials were prepared using the thermal chemical vapor deposition with ${C_2}{H_2}$ on the Ni-graphite mixture as a supported catalyst. The samples were identified by SEM, TEM, Raman spectroscopy, and the hydrogen storage measurement by electrochemical method was also carried out. The purity of carbon nanotube prepared using ground mixture was higher than that of unground one. Also, the amount of hydrogen storage of purified carbon nanomaterials was more than that of unpurified one.

지지촉매로 Ni-graphite를 사용하고 ${C_2}{H_2}$를 이용한 열화학기상증착법에 의하여 탄소나노소재를 합성하였다. 합성된 시편은 SEM, TEM, 라만 분광법으로 분석하였으며, 수소저장특성은 전기화학적인 방법에 의하여 평가하였다. 탄소나노소재 합성시 메카노케미컬 처리과정을 거친 시편이 거치지 않은 시편에 비하여 탄소나노튜브의 순도가 우수하였다. 한편, 탄소나노소재를 정제함에 따라 수소저장특성이 크게 향상되었다.
