Abstract:
A method for the manufacture of carbon fibrils comprising passing a fibril-forming feed stock under temperature and pressure conditions suitable for formation of fibrils over a fibril-forming catalyst, wherein said fibril-forming catalyst is produced by a method comprising contacting a carboxylate, in an amount effective to enhance the yield of carbon fibrils produced over the yield which would be produced without said carboxylate, with said fibril-forming catalyst, wherein said fibril-forming catalyst comprises at least one fibril-forming catalyst metal from a metal-containing inorganic precursor compound and said carboxylate is from a carboxylate precursor, said metal-containing precursor compound being different from the carboxylate, said metal-containing precursor compound also being different from the carboxylate precursor.
