摘要
Abstract
In the present study we studied the influence of the mass of ferrocene precursors on the synthesis of carbon nanotubes with methane and oxygen as the explosive sources.The morphology and structure of the carbon nanotubes were characterized using X-ray diffraction,transmission electron microscopy and high resolution transmission electron microscopy technologies.The results indicate that when the ferrocene quantity is small only carbon coated iron nanoparticles exist in the products.With the increase of the ferrocene mass,carbon nanotubes are gradually produced with their diameters ranging from 10 to 50 nm,which are multi-walled carbon nanotubes.With the increase of the precursor mass,the degree of the graphitization of the carbon nanotubes is also increased but the structural defects are reduced.In addition,by the thermogravimetric analysis of the synthetic product,it can be concluded that the gaseous detonation synthesis of carbon nanotubes has a great ability of oxygen absorption,and the content of carbon nanotube in the sample is about 26％.关键词
