METHOD AND APPARATUS FOR SYNTHESIZING FILAMENTARY STRUCTURES

摘要

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 unsupporte d catalyst to synthesize the filamentary structure in a post-flame region of t he flame. Residence time is selected to favor filamentary structure growth.
