以铁基合金薄膜为催化剂，在玻璃衬底上溅射乙炔，在600~700℃下催化裂解乙炔，制备出纯度较高的螺旋状纳米扭曲碳纳米带或碳纳米线圈。用Fe-SEM和HR-TEM对碳的构象进行了表征。螺旋状纳米结构由一条宽度为100-200 nm的扁平带状结构组成，螺距约为150 nm。纳米结构分析表明，该碳构象具有轻微的石墨化结晶度。
Twisting carbon nano-ribbons or carbon nanocoils with a helical nanostructure was synthesized with a high purity by the catalytic pyrolysis of acetylene at 600–700 °C using Fe-base alloy films as a catalyst sputter coated on the glass substrates. FE-SEM and HR-TEM were applied to characterize the carbon conformation. The helical nanostructure was composed of one flat ribbon with a width of 100–200 nm, twisting in a pitch of about 150 nm. The nanostructure analysis revealed that this carbon conformation was of slightly graphitic crystallinity.
