Abstract
Method and apparatus for producing filamentary structures. The structures include single-walled nanotubes. The method includes combusting hydrocarbon fuel and oxygen to establish a non-sooting flame and providing an unsupported catalyst to synthesize the filamentary structure in a post-flame region of the flame. Residence time is selected to favor filamentary structure growth.
Claims31
A method for producing filamentary structures comprising:
- combusting a premixed mixture comprising hydrocarbon fuel and oxygen, in the presence of an unsupported catalyst, to establish a non-sooting flame and to produce the filamentary structures from the combusted hydrocarbon fuel and the unsupported catalyst in a post-flame region of the non-sooting flame while maintaining the non-sooting flame.
