Embodiment Construction

[0019] see figure 1 , The equipment of the present invention includes: a reactor 1; a first electrode 13 and a second electrode 15 are arranged in the above-mentioned reactor 1 in a manner opposite to each other; an arc generating device 12, which includes a power supply (not shown) , used to provide current between the above-mentioned first electrode 13 and a second electrode 15; a metal heating source 16 is arranged near the above-mentioned two electrodes and a gas supply device (not shown).

[0020] The reactor 1 described in this equipment is a reactor for preparing carbon nanotubes by an arc discharge method, which has good airtightness and can withstand high pressure. The above-mentioned reactor 1 is also equipped with a water cooling device (not shown in the figure), which is used to cool the reactor and electrodes during the preparation of carbon nanotubes. Fast and uniform electrodes can grow longer carbon nanotubes.

The equipment includes one reactor; one first electrode and one second electrode set inside the reactor oppositely; one electric arc generator including power supply for providing current between these two electrodes; one metal heating source set near the electrodes and one gas supplier. The present invention also provides the preparation process of carbon nanotube embedded into metal, and the preparation process includes the following steps: vacuumizing the reactor and introducing protecting gas; starting the electric arc generator for electric arc discharge; and heating to gasify metal to be embedded and to produce carbon nanotube embedded into metal.

Description

【Technical field】 [0001] The invention relates to a preparation device and method for carbon nanotubes, in particular to a preparation device and method for metal-embedded carbon nanotubes. 【Background technique】 [0002] Carbon nanotubes are a new type of carbon material, discovered by Japanese researcher Iijima in 1991, please refer to "Helical microtubules of graphitic carbon", S Iijima, Nature, vol.354, p56 (1991). Due to the excellent properties of carbon nanotubes, their applications have been widely concerned, and hydrogen storage capacity is one of their important applications. [0003] The hydrogen storage capacity of carbon nanotubes has been widely studied, and it is generally believed that the hydrogen storage capacity of pure carbon nanotubes is about 5wt%. Embedding alkali metals in carbon nanotubes can greatly improve the hydrogen storage capacity of carbon nanotubes. P.Chen, X.Wu and others published an article titled "HighH2 Uptake by Alkali-Doped Carbon N...
