摘要
Abstract
The carbon precursor of sucrose was prepared by K2 CO3 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℃,K2 CO3 concentration of 0.5mol/L,weight ratio of F127 to starch of 1∶3,reation temperature of 45℃,reaction time of 12h.关键词
