Pyrolysis Flame Synthesis of Single, Double and Triple-walled Carbon Nanotubes on Fe/Mo/Al2O3 Catalysts:Effects of Synthesis Temperature, Sampling Time and Flow Rate of CO
摘要
Abstract
Single, double and triple-walled carbon nanotubes were synthesized by pyrolysis flame using substrate-support catalyst Fe/Mo/Al2O3 and CO as carbon source via oxyacetylene pyrolysis flame. The effects of synthesis temperatures, sampling time and flow rate of carbon source gas on the synthesized product were studied. It is found that a synthesis temperature of 830 °℃ can provide high temperature environment to synthesize single, double and triple-walled carbn nanotubes and eliminate wrapped substrate-support catalyst polymers on carbon nanotubes, then make a substantial increase in production. When sampling time is 10 min and CO flow rate is 0.4 L/min, substrate-support catalyst polymer clusters can be perfectly smashed, then further optimize products and increase production.关键词
