【摘要】 介绍了一种既简单又经济的用于制备Y形结构碳纳米纤维的催化燃烧方法。采用乙醇作为碳源,金属盐溶液作为催化剂先体;同时,基底材料采用铜薄片;实验装置采用酒精灯。实验在常温常压下就可以进行,且不需要引入其他辅助生长Y形结的气体。实验结果表明,该方法具有一定的实用性,可实现大量制备;透射电镜分析结果表明,产物中所含Y形结结构丰富,如螺旋结构、非螺旋结构以及螺旋与非螺旋混合的结构。更多还原

【Abstract】 A simple and economical method for synthesizing Y-like carbon nanofibers was introduced.Ferric nitrate and nickel nitrate were used as the catalyst precursor,respectively.Y-shaped structure was synthesized by the interaction of ethanol with catalyst precursor on the copper plate at room temperature,without directly seeding catalyst into the flame.The results indicate that the method has a practicability in a great degree and the Y-type carbon products are rich in structures such as helical,nohelical and hybrid structure.更多还原
