摘　　要：通过改进的室温一步法制备了MWCNTs/MOF-5杂化材料,分别用XRD、FT-IR、TEM、FESEM、比表面积和孔隙度分析仪对MOF-5,MWCNTs/MOF-5进行了表征和分析。结果表明,碳纳米管的引入对晶体结构的影响不大;复合方式为碳纳米管"穿插"MOF-5的结构;MOF-5和MWCNTs/MOF-5在77 K和100 k Pa下N2吸附量最大,分别为873,743 cm-3/g,比表面积(BET)分别为2 435,1 866 m2/g。In this study,the MWCNTs / MOF-5 hybrid materials have been synthesized by an improved method via one step at room temperature. The resulting samples were characterized and analyzed by XRD,FT-IR,TEM,FESEM and the specific surface area and porosity analyze,respectively. The results show that the presence of MWCNTs do not affect the origin structure of MOF-5 in MWCNTs / MOF-5,the resulted MWCNTs / MOF-5 exhibits the 'penetration'structure which MWCNTs was penetrated through the MOF-5 plate,the specific surface area( BET) of MOF-5 and MWCNTs /MOF-5 ware 2 435 and 1 866 m2/ g; the maximum N2 adsorption capacity are 873 and 743 cm- 3/ g at 77 K and 100 k Pa.
