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.
使用介孔硅质材料SBA - 15作为模板合成了有序介孔碳CMK - 3。对CMK - 3进行了表征，并将其用于富勒烯C60和C70的吸附。发现CMK - 3的吸附容量比活性炭高4倍。研究了C60和C70在CMK - 3上的单体系和双体系吸附平衡等温线。还探讨了富勒烯在CMK - 3上吸附的可逆性。结果表明，CMK - 3是一种通过吸附分离富勒烯的有效且可逆的吸附剂。
