摘要:
以甲烷为碳源，分别以2CoO·5V2O5载体、Fe2O3·5V2O5载体和2NiO·5V2O5载体为催化剂，采用化学气相沉积(CVD)法通过催化裂解甲烷在800 ℃制备出多壁纳米碳管（MWNTs）.对这三个产品进行了扫描电子显微镜、高分辨率透射电子显微镜和激光拉曼光谱表征.结果表明：利用含钒的双金属催化剂可有效制备出石墨化程度高的多壁纳米碳管.
Abstract:
MWNTs with highgraphitic degree have been synthesized by catalytic chemical vapour deposition of CH4 over three vanadium containing catalysts (2CoO·5V2O5/MgO、Fe2O3·5V2O5/MgO and 2NiO·5V2O5/MgO) at 800 ℃. The morphologies and microscopic structure of the prepared MWNTs were characterized by SEM、 HRTEM and Raman spectroscopy. The results indicated that MWNTs with highgraphitic degree could be successfully prepared by using the vanadiumcontaining bimetallic catalysts. In addition， high yield of multiwall carbon nanotubes could be obtained using 2NiO·5V2O5/MgO as catalyst， compared with Fe2O3·5V2O5/MgO and 2CoO·5V2O5/MgO catalyst. This result showed that 2NiO·5V2O5/MgO catalyst has a higher catalytic activity among the three catalysts.
