SOL-GEL FABRICATION METHOD OF CATALYST FOR SYNTHESIZING THIN MULTIWALLED CARBONNANOTUBE AND CARBONNANOTUBE MASS SYNTHESIZING METHOD USING THE CATALYST

摘要

A method for producing catalytic for synthesizing a fraction wall multi-walls carbon nanotube is provided to synthesize massively a fraction wall multi-walls carbon nanotube of which purity is high, a diameter is 3 - 10 nm and a number of graphite wall is less. A method for producing catalytic for synthesizing a fraction wall multi-walls carbon nanotube comprises steps of: (S1) dissolving raw materials of iron and magnesium and a chelate agent in water; (S2) adding a raw material of molybdenum in a solution in which the raw material of the iron and the raw material of magnesium are dissolved; (S3) mixing the raw material of the iron and the raw material of the magnesium and the chelate agent and the raw material of the molybdenum while being heated at predetermined temperature; (S4) heating in order to diversified the raw material of the iron and the raw material of the magnesium and the chelate agent and the raw material of the molybdenum are mixed to a gel state material; (S5) heating up the gel state material and being diversified to the solid material; (S6) being diversified to powder by grinding a solid material; and (S7) reducing the powder under a hydrogen atmosphere.
