Abstract

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

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。
