The synthesis of Multi-Walled Carbon Nanotubes (MWCNTs) by Chemical Vapor Deposition (CVD) is becoming most ideal method for producing large quantity of CNT at different temperature conditions. Nano-porous materials such as transition metal carbonates with bimetallic alloy catalyst were used to fabricate MWCNTs with high yield and less amorphous carbon. In the present research work, the MWCNTs were successfully fabricated using Fe-Ni bimetallic catalyst on CaCO3 support with the 180% optimum yield. The proposed yield was high and less-cost effective catalysts to other methods. The yield of MWCNTs depends on four parameters such as growth time (30/45 min), growth temperature (700/730 oC), acetylene flow rate (150/190 ml/min) and argon flow rate (800/900 ml/min). The impact of the reaction temperature and the flow rates were observed to be most significant on the high yield of MWCNTs.

Abstract


The synthesis of Multi-Walled Carbon Nanotubes (MWCNTs) by Chemical Vapor Deposition (CVD) is becoming most ideal method for producing large quantity of CNT at different temperature conditions. Nano-porous materials such as transition metal carbonates with bimetallic alloy catalyst were used to fabricate MWCNTs with high yield and less amorphous carbon. In the present research work, the MWCNTs were successfully fabricated using Fe-Ni bimetallic catalyst on CaCO3 support with the 180% optimum yield. The proposed yield was high and less-cost effective catalysts to other methods. The yield of MWCNTs depends on four parameters such as growth time (30/45 min), growth temperature (700/730 oC), acetylene flow rate (150/190 ml/min) and argon flow rate (800/900 ml/min). The impact of the reaction temperature and the flow rates were observed to be most significant on the high yield of MWCNTs.
