摘要

首次选用交联剂乙二醛,以壳寡糖为碳氮源、F127为软模板,用低浓度水热合成法制备孔径均匀的介孔碳。采用热重、N₂吸附/脱附和小角X射线衍射等表征手段分析介孔碳的性质,探讨了乙二醛用量、F127与壳寡糖质量比及原料添加顺序对介孔碳孔结构的影响。结果表明:N成功掺杂到介孔碳中,其质量分数为4.84%;乙二醛添加量2mL、原料中F127与壳寡糖的质量比为0.333、碳源滴加到模板中时,所制备的介孔碳孔径主要分布在5～10nm之间,平均孔径约7.62nm,其比表面积和介孔孔容分别为473m²/g和0.37cm³/g,有望提高材料的吸附性能。

Abstract

First the cross-linking agent glyoxal(GL) was selected,homogeneous mesoporous carbon was prepared by low concentration hydrothermal synthesis method which using chitosan-oligosaccharide(COS) as C—N source,F127 as soft template.The influence of GL amount,the mass ratio of F127 to COS and the order of adding raw materials on pore structure of porous carbon was investigated by using TG,BET,XRD,SEM and XPS.The results shown that nitrogen was successfully doped in-situ into mesoporous carbon materials,and its content was 4.84 % and the uniform carbon was prepared as follows: the amount of GL was 2mL,the value of F127/COS was 0.333,and the carbon source was dropped into the template,the pore size was mainly distributed between 5～10nm,the average pore size of mesoporous carbons was about 7.6nm.The specific surface area and mesopore volume were 473m²/g and 0.37cm³/g.The addition of GL improved the pore structure of the materials.
