“液体电弧”方法是最近提出的一种经济有效的技术，用于制造碳纳米材料，不需要真空设施。目前，需要研究液体组分对该方法合成的产品的影响。在本研究中，液体苯 (C6H6) 用于“液体电弧”方法。结果，在电极之间形成的沉积物中发现了直径10-30nm的多壳纳米粒子，其中高度卷曲的石墨结构似乎占多数。重要的是，在这种条件下不会形成碳纳米管，这与水或液氮中的电弧不同。另外，确认了在现有条件下无法生成富勒烯。
‘Arc in liquid’ method is a cost-effective technique lately proposed to fabricate carbon nanomaterials, which does not require vacuum facilities. Currently, it is demanded to examine the effect of liquid components on the products synthesized by this method. In this study, liquid benzene (C6H6) was used in the ‘arc in liquid’ method. As a result, multi-shelled nanoparticles of diameter 10–30nm were found in the deposits formed between electrodes, in which highly curled graphitic structure seemed majority. Importantly, CNTs are not formed in this condition, which is different from arc in water or liquid nitrogen. In addition, it was confirmed that fullerene was not produced by the present condition.
