摘　　要：以几种沸石矿为模板、蔗糖为碳源,通过模板法制备了多孔炭,并用 77K氮气吸附和X射线衍射仪(XRD)进行了表征。结果表明:此方法可以制备出具有一定比表面积和较大中孔容积的多孔炭,其中孔率随着模板中孔容积的增大而增加,但在所制多孔炭中存有少量的杂质。Porous carbons were prepared with zeolite minerals as templates and sucrose as carbon source and characterized by N-2 adsorption and XRD analysis. It was found that porous carbons with high mesopore volume could be obtained by this method. In addition, the mesoporosity of resultant carbons increases with increasing amount of template. However, a small amount of impurity is found in the resultant carbons derived from zeolite minerals.
