成型方式对铜基金属有机骨架材料甲烷吸附性能的影响
Effect of molding methods on CH4 adsorption capacity of Cu-based metal-organic framework
摘要
Abstract
Cu-based metal-organic framework HKUST-1 was prepared by magnetic stirring method.The resulting HKUST-1 powders A were molded by extrusion and centrifugal granulation.The effects of different samples on CH4 uptake were investigated.The crystal structure and microstructure of different samples were analyzed by XRD,TEM and N2 adsorption desorption.The results showed that more crystal structure and microstructure were preserved in centrifugal granulation sample C.Damaged microstructure of HKUST-1 in extrusion sample B was higher than sample C.Experimental results showed that CH4 uptakes of the sample A,B and C were 215,63,130 cm3/g,respectively.With the same binding agent and dosage,the physicochemaical properties of sample B was lower than that of sample C,which can be explained by the reason that molding method was causing the difference between the molded bodies from HKUST-1 powders.关键词
