Multi-wall carbon nanotubes (MWCNT) were prepared by spray-pyrolysis of alpha-pinene, a botanical hydrocarbon, and ferrocene as catalyst at 900 degrees C. The MWCNT were analyzed by scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), and Raman spectroscopy. The microscopy studies show the formation of carbon nanotubes with diameters between 20 and 30 nm and length greater than one hundred microns. Nanoparticles were detected outside and inside the nanotubes and were identify as metallic iron and iron carbide, respectively. Raman spectroscopy reveals that the alpha-pinene grown carbon nanotubes are graphitized showing both the D and G bands at 1335 cm(-1) and 1585 cm(-1) respectively.
多壁碳纳米管（MWCNT）通过对植物性碳氢化合物α-蒎烯和二茂铁作为催化剂在900℃下进行喷雾热解制备而成。采用扫描电子显微镜（SEM）、高分辨率透射电子显微镜（HRTEM）和拉曼光谱对多壁碳纳米管进行了分析。显微镜研究表明形成了直径在20至30纳米之间且长度大于一百微米的碳纳米管。在纳米管的外部和内部均检测到了纳米颗粒，分别鉴定为金属铁和碳化铁。拉曼光谱显示，由α-蒎烯生长的碳纳米管已石墨化，分别在1335厘米-1和1585厘米-1处显示出D带和G带。
