【摘要】 该文研究了采用无水乙醇作为碳源,利用化学气相沉积法(CVD法)制备纳米碳管的制备工艺,并运用TEM、Raman光谱等方法对制备的样品进行分析,讨论了碳纳米管形态、结构,及其与催化剂和生长条件之间的关系。实验表明,相比于其他方法合成的碳纳米管,利用无水乙醇分解制备的碳纳米管具有大内径、缺陷少和顶端开口的特点,在储氢等方面应具备更为优良的效果,从而有着潜在的应用前景。更多还原

【Abstract】 The method of chemical vapor deposition (CVD) has been applied in the synthesis of carbon nanotubes (CNTs) with alcohol as carbon source. By means of TEM and Raman spectrum methods, the morphology and structure of carbon nanotubes have been investigated, and the relationship between these CNTs and the experimental parameters such as catalysts and reaction conditions has been discussed. It is indicated that compared with the CNTs synthesized in other methods, CNTs synthesized here have bigger inside diameter, fewer defects and open ends when the experimental parameters are controlled stably. CNTs of these structures have better performances in hydrogen-storage and so on, and have greater potential applications.更多还原
