摘要：

Carbon nanocoils with controlled diameters have been synthesized by thermal chemical vapor deposition using carboxylic acid metals as a precursor of the catalyst. It has been found that the line diameter of the nanocoils is determined by the size of the catalyst particles which can be controlled by adjusting the concentration of carboxylic acid metals in the solution. It is confirmed that the coil diameter of the nanocoils is proportional to the size of the catalyst particles. This is consistent with a proposed hodograph of carbon extrusion from a catalyst particle.
