摘要：以碳纳米管(CNTs)作"种子",液体石蜡和三聚氰胺分别作碳源和碳/氮源,利用爆炸辅助化学气相沉积法在CNTs"种子"上合成出新的CNTs和氮掺杂碳纳米管(CNx)。透射电镜(TEM)和电子能量损失谱(EELS)测试表明:新合成的CNTs具有空心管状结构,而CNx呈竹节状且氮的原子分数高达17.3%。CNTs"种子"的作用归因于其端部的纳米级弯曲和开放性边缘具有吸附并外延Cn/CN物种的功能。
Carbon and nitrogen-doped carbon（CNx） nanotubes were synthesized by detonation-assisted chemical vapor deposition with CNTs as seeds and paraffin as the carbon source and melamine as the carbon/nitrogen source.Transmission electron microscopy and electron energy loss spectroscopy were performed to characterize both materials.CNx nanotubes exhibited a compartmentalized bamboo-like structure and contained a high concentration of nitrogen（17.3 at %）,while the new pure CNTs had hollow cores.The role of the original CNTs added to the raw materials could be ascribed to their curvature and open tip edges,which adsorbed Cn/CN species and assembled them into carbon and CNx nanotubes.
