用改进的石墨电弧放电方法制备了小直径、高质量的碳纳米管,以水为打弧介质,氢气为保护气体.该方法具有装置简单,电流小,无催化剂,制备出的多壁碳纳米管直径小于10nm等优点.
A simplified hydrogen-assisted arc discharge method is developed in water under low current for the production of high quality multi-wall carbon nanotubes without catalyst. The average diameter of as-synthesized carbon nanotubes is less than 10 nm.
