We report the formation of bamboo-shaped carbon-nitrogen nanotubes by employing a simple, one-step and economically viable spray pyrolysis technique using new precursor; acetonitrile and ferrocene solution. By varying the concentration of ferrocene with respect to acetonitrile, it has been found that the optimum concentration of ferrocene in acetonitrile is 5 mg/ml. The special feature of the as-synthesized bamboo-shaped carbon-nitrogen nanotubes bundles is that they are produced in a high yield (1.25 gms/run). They also have long linear extents (approximately 430 microm) and are very clean. The average composition of carbon-nitrogen nanotubes comes out to be C26N.
我们报告了通过使用一种简单、一步且经济可行的喷雾热解技术，以新型前驱体乙腈和二茂铁溶液制备竹状碳氮纳米管的过程。通过改变二茂铁相对于乙腈的浓度，发现乙腈中二茂铁的最佳浓度为5毫克/毫升。所合成的竹状碳氮纳米管束的特殊之处在于它们能高产率制备（每次运行1.25克）。它们还具有较长的线性长度（约430微米）且非常纯净。碳氮纳米管的平均组成是C26N。
