以羧酸金属为催化剂的前驱体，通过热化学气相沉积法合成了直径可控的碳纳米线圈。已经发现，纳米线圈的线直径由催化剂颗粒的尺寸决定，催化剂颗粒的尺寸可以通过调节溶液中羧酸金属的浓度来控制。证实纳米线圈的线圈直径与催化剂颗粒的尺寸成比例。这与所提出的碳从催化剂颗粒中挤出的速端图一致。
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.
