摘要

Graphite electrodes were used for the direct current (DC) arc discharge in water.And high-resolution transmission electron microscopy (HRTEM) was used to investigate the products.Based on the experimental phenomena and nano-structure products,arc plasma characteristics in water were analyzed theoretically.Two growth regions and relevant growth modes were proposed to interpret the formation mechanisms of nano-struetures by are discharge in water.Furthermore,liquid nitrogen and cross magnetic field was applied to change the arcing state respectively,and new carbon nano-struetures were obtained.Their formation mechanisms were also analyzed correspondingly.
