چکیده

An ordered mesoporous carbon, CMK-3, was synthesized using a mesoporous siliceous material, SBA-15, as the template. CMK-3 was characterized and used for the adsorption of fullerenes C60 and C70. It was found that the adsorption capacity of CMK-3 is 4 times higher than that of activated carbon. The adsorption equilibrium isotherms of C60 and C70 on CMK-3 were studied for both single and binary systems. The reversibility of fullerene adsorption on CMK-3 was also explored. The results showed that CMK-3 is an effective and reversible adsorbent for the separation of fullerenes by adsorption.
