摘要/Abstract

摘要： 以纯硅MCM-48为模板、对甲苯磺酸为催化剂、糠醇为碳源成功制备了高度有序的中孔炭分子筛.结果表明,采用真空浸渍法能较好的将酸性催化剂对甲苯磺酸引入MCM-48孔道内.所用糠醇的体积用量为MCM-48孔体积的2.5倍为宜.产物用XRD、TEM、N₂吸附等进行了表征,表明所制得的中孔炭具有规整的三维孔道结构,平均孔径3.1nm,孔容0.96m³/g,比表面积113.6m²/g.此外,还发现二次炭化有利于提高中孔炭的热稳定性.

关键词: 中孔炭分子筛, 糠醇, MCM-48

Abstract: Ordered mesoporous carbon was successfully prepared using siliceous MCM-48 as template, p-toluenesulfonic acid (PTSA) as catalyst, and furfuryl alcohol as carbon source. It was found that under vacuum infiltration condition, PTSA could be introduced deeply into the holes of MCM-48. The suitable volume of furfuryl alcohol was 2.5 fold of the pore volume of MCM-48. The product was characterized by X-ray powder diffraction, transmission electron microscopy and N₂ adsorption-desorption. The characterization results indicated that mesoporous carbon exhibited ordered 3-D pore structure, with a mean pore size of 3.1 nm, a pore volume of 0.96 m³/g,and a specific surface of 1513.6 m²/g. It was also found that thermal stability of mesoporous carbon could be enhanced through re-carbonization of the carbon.

Key words: mesoporous carbon, furfuryl alcohol, MCM-48
