Abstract:
    A method for producing fullerenes, characterized in that said method includes a step (a) of contacting an aromatic compound-containing starting material with a supercritical fluid or a subcritical fluid in the presence of a transition metal element-containing catalyst at a temperature in a range of from 350 to 800 DEG C and at a pressure in a range of from 3 to 50 MPa. Said supercritical fluid or said subcritical fluid is formed from one or more kinds of materials selected from the group consisting of an aromatic compound as said starting material, a solvent for said aromatic compound, a solvent for said catalyst, water, dinitrogen monoxide, and ammonia.
