通过氢弧等离子体法制备的铁纳米颗粒催化乙炔热解，在不同温度下合成了碳纳米纤维（CNF）和碳纳米管（CNT）。通过透射电子显微镜和场发射扫描电子显微镜对所得碳纳米材料进行了表征。铁纳米粒子总是位于CNF或CNT的尖端，其直径与铁纳米粒子的直径大致相同。产物的结构与反应温度密切相关，只需升高温度即可从纤维变为管状。 CNF 是在 550–650 °C 的反应温度下获得的。当反应温度升高到710-800°C时，获得了碳纳米管。
Carbon nanofibers (CNFs) and carbon nanotubes (CNTs) were synthesized at different temperatures by the catalytic pyrolysis of acetylene with iron nanoparticles prepared using a hydrogen-arc plasma method. The obtained carbon nanomaterials were characterized by transmission electron microscopy and field-emission scanning electron microscopy. An iron nanoparticle was always located at the tip of CNFs or CNTs, whose diameter was approximately identical with the diameter of the iron nanoparticle. The structures of the products were closely related to the reaction temperature, and could be changed from fibers to tubes by simply increasing the temperature. CNFs were obtained at the reaction temperature of 550–650 °C. When the reaction temperature was increased to 710–800 °C, CNTs were obtained.
