摘　　要：以两种沸石矿为模板、糖醇为炭源,通过模板法制备了多孔炭,并研究了草酸为催化剂对制备得到的炭的影响。通过77K氮气吸附对制备得到的炭进行表征。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;而对于草酸,它的使用使得沸石的微孔骨架被部分破坏,从而使制备得到的多孔炭的微孔容积减小。<Abstrcat>The porous carbons were prepared by using two zeolite minerals as templates and furfuryl alcohol as carbon source by a template method and study on effect with the oxialic acide as the catalyst on the carbon.The samples were characterized by N_2 adsorption at 77 K.It was found that porous carbon materials with certain amount of specific surface area,mesopores could be obtained by the present method.In addition,the use of the oxalic acid as the catalyzer resulted in the decrease of pore volume of the carbons due to the pore structure of the zeolite minerals destroyed by the oxalic acid.
