以四氢萘和四水合乙酸镍的混合物作为前驱体,采用高温自生压催化热解法在不同温度下制备碳纳米管、碳纳米胶囊。通过SEM、TEM、XRD和VSM对产物进行了表征测试。结果表明,随着反应温度的上升,产物中碳纳米管数量呈递增趋势。从800℃到1 000℃,碳纳米管的平均直径逐渐减小。催化剂的去活化作用导致了碳纳米胶囊结构的形成。
Using a mixture of tetrahydronaphthalene and nickel acetate tetrahydrate as precursors, carbon nanotubes and carbon nanocapsules were prepared at different temperatures by high temperature autocatalysis catalytic pyrolysis. The products were characterized by SEM, TEM, XRD and VSM. The results showed that with the increase of reaction temperature, the amount of carbon nanotubes in the product showed an increasing trend. From 800 ° C to 1000 ° C, the average diameter of the carbon nanotubes gradually decreases. Deactivation of the catalyst led to the formation of a carbon nanocapsule structure.
