Tri-Metallic Catalyst for Mass Production of Quasi-Aligned Carbon Nanotubes by Thermal Chemical Vapor Deposition

摘要：

　　In this paper,mass production of quasi-aligned CNTs was achieved with a new tri-metallic catalyst (Fe-Ni-Mo/MgO) by thermal CVD method,using methane as carbon precursor.The growth process was in-situ monitored by thermal gravimetry/differential scanning calorimetry (TG-DSC) technique,and the yield of CNTs over 2200% was attained under the mixture atmosphere of CH4 and H2 with flow rate about 25 ml/min and 5 ml/min respectively at 900℃ for 30 min.The as-prepared products were characterized.Raman spectrums showed that the CNTs are multi-wall structure.The diameter of the CNTs was estimated to be 20-30 nm.We think the synergism of FeNi3 alloy and Mo is the main reason for the high catalytic activity oftri-metallic catalyst.
