一种提高单壁碳纳米管产率的新方法技术

本发明专利技术公开了一种提高单壁碳纳米管产率的新方法，主要是基于浮动催化裂解法而实施，所述浮动催化裂解法包括：通过载气将碳源和催化剂带入高温反应区，并在选定温度下合成单壁碳纳米管；其中，所述新方法包括：将所述选定温度提高至1000-1400℃，尤为优选的是1200-1350℃。本发明专利技术提供了仅仅通过提高反应温度而增加单壁碳纳米管产率的方法，其无需改变配方，亦不会改变单壁碳纳米管的结构或形态，并能有效提升单壁碳纳米管结晶度，还易于实施和调控，同时安全环保，适用于规模化生产优质单壁碳纳米管。

A new method for increasing the yield of single-walled carbon nanotubes

The present invention discloses a new method for improving the yield of single-walled carbon nanotubes, is mainly the implementation of floating catalyst method based on the floating catalytic pyrolysis method includes: through the carrier gas of carbon source and catalyst into the high temperature reaction zone, and synthesis of single-walled carbon nanotubes in selected temperature; among them, including the new methods: the selected temperature increased to 1000-1400 DEG C, particularly preferably 1200-1350 DEG C. The present invention provides only by increasing the reaction temperature and the increase of single wall carbon nanotubes yield, without changing the formula, will not change the structure or morphology of single-walled carbon nanotubes, and can effectively improve the crystallinity of single-walled carbon nanotubes, is easy to implement and control, and safety and environmental protection, suitable for large-scale production high quality single walled carbon nanotubes.
