Carbon nanotubes have been synthesized by chemical vapor deposition at 850°C using silkworm cocoons as a precursor. The impregnation method with 3 wt% ferrocene as a catalyst was utilized for growth of carbon nanotubes. The flow rates of C₂H₂, H₂, and N₂ were fixed at 100, 150, and 350 ml/min, respectively. Morphology, microstructure and quality of the synthesized carbon nanotubes were investigated by scanning electron microscopy, transmission electron microscopy, and Raman spectroscopy techniques. Results showed that the prepared carbon nanotubes were multiwalled and good graphitic quality. When used as the cathode material for aluminum-air battery, prepared carbon nanotubes cathode exhibited higher current density than commercial graphite cathode. Based on our study, there is a successful conversion of silkworm cocoons into value-added nanomaterial products, promoting the natural biotechnological materials.

碳纳米管已经通过使用蚕茧作为前体在850°C的化学气相沉积法合成。以3重量％的二茂铁为催化剂的浸渍方法用于碳纳米管的生长。C ₂ H ₂，H ₂和N ₂的流量分别固定为100、150和350 ml / min。通过扫描电子显微镜，透射电子显微镜和拉曼光谱技术研究了合成碳纳米管的形貌，微观结构和质量。结果表明，所制备的碳纳米管是多层的，石墨质量良好。当用作铝-空气电池的阴极材料时，制得的碳纳米管阴极显示出比市售石墨阴极更高的电流密度。根据我们的研究，成功地将蚕茧转化为高附加值的纳米材料产品，从而促进了天然生物技术材料的发展。
