摘要: 以蔗糖为碳源,F127为表面活性剂,采用K2CO3活化合成蔗糖碳前体,在氮气保护下炭化制备碳分子筛。通过SEM、FTIR和N2-吸/脱附手段对碳分子筛样品进行表征,优化样品制备工艺过程。结果表明,在炭化温度为800℃下,活化剂K2CO3浓度为0.5mol/L,F127/蔗糖质比1:3,反应温度45℃,反应时间12h制备的碳分子筛表面孔结构显著,孔隙发达,比表面积高达1366.4423m2/g,孔容为0.865796cm3/g,孔径集中在0.64nm。

Abstract: The carbon precursor of sucrose was prepared by K2CO3 activation synthesis method in which used sucrose as carbon source,F127 as surfactant,carbon molecular sieve obtained by carbonization under nitrogen protection.The samples were characterized by SEM,FTIR and N2-adsorption desorption to optimize the sample preparation process.The results showed that the obtained samples that was the remarkable surface pore structure and the pore developed was composed of a high specific surface area of 1366.4423m2/g,Aperture concentration in 0.64nm a single point of pore volume of 0.865796cm3/g under the condition of carbonization temperature 800℃,K2CO3 concentration of 0.5mol/L,weight ratio of F127 to starch of 1:3,reation temperature of 45℃,reaction time of 12h.

Key words: sucrose, K2CO3, chemical activation, carbon molecular sieve
