One-step Preparation of Highly Dispersed Metal-supported Catalysts by Fluidized-bed Mocvd for Carbon Nanotube Synthesis

Catalysts play a pivotal role in modern industries, especially in the petrochemical industry, such as in the processes for production of advanced materials such as carbon nanotubes. Since the discovery by Iijima in 1991, carbon nanotube has received increasing interest worldwide owing to their unique structural, electronic and mechanical properties [1], and their promising applications in molecular electronics [2] and hydrogen storage [3], etc. Chemical vapor deposition (CVD) of hydrocarbons proves to be an efficient method to synthesize single-walled and multi-walled carbon nanotubes [4].
