알루미나 지지 코발트-철 촉매는 3가지 다른 조건, 즉 핫플레이트(A), 초음파 처리(B) 및 침지(C)를 적용하여 습식 함침 방법을 사용하여 제조되었습니다. 알루미나 담지 코발트-철 촉매는 촉매 화학 기상 증착(CCVD) 기술을 사용하여 다중벽 탄소 나노튜브(MWNT)의 합성에 적용되었습니다. 코발트-철 촉매의 형태와 입자 크기 및 MWNT 수율은 전계 방출 주사 전자 현미경(FE-SEM)으로 조사했으며 샘플의 표면 원소 조성은 에너지 분산 X선 분석(EDX)으로 얻었습니다. 촉매 A, B 및 C의 형태는 서로 다른 것으로 밝혀졌으며, 입자 크기는 20-40 nm 범위였습니다. 샘플 A, B 및 C로부터 생성된 MWNT의 직경은 촉매 입자 크기와 관련이 있는 것으로 밝혀졌으며, 따라서 촉매 입자가 작을수록 더 얇은 MWNT가 얻어졌습니다. 더 작은 직경의 MWNT는 나노튜브 표면에 비정질 탄소가 없기 때문에 더 높은 순도와 품질로 얻어졌습니다. 따라서 원하는 직경의 MWNT를 합성하기 위해 다양한 촉매 제조 방법으로 인해 촉매 입자의 크기가 달라졌습니다.

Abstract: Alumina supported cobalt-ferrum catalysts were prepared using wet impregnation method by applying 3 different conditions, namely hotplate (A), sonication (B) and soaking (C). The alumina supported cobalt-ferrum catalysts were applied in the synthesis of multi-walled carbon nanotubes (MWNTs) using catalytic chemical vapour deposition (CCVD) technique. The morphology and particle size of the cobalt-ferrum catalysts and the MWNTs yield were examined by field emission-scanning electron microscopy (FE-SEM) while the surface elemental composition of the samples was obtained by energy dispersive X-ray analysis (EDX). The morphology of catalysts A, B and C were found to be different, the particle sizes were ranged from 20-40 nm. The diameters of the MWNTs yield from samples A, B and C were found to be related to the catalyst particle size, thus the smaller the catalyst particle, the thinner the MWNTs obtained. The MWNTs with smaller diameter were obtained with higher purity and quality becuase the nanotube surface are free from amorphous carbon. Therefore, different catalyst preparation methods resulted in different sizes of the catalyst particle in order to synthesize MWNTs with desired diameter.
