Abstract: By using the precursor impregnation procedure,copper ion was loaded in the mesopores in MSU-s which shows higher hydrothermal stability and stronger acidity. Copper-containing mesoporous was synthesized. At the mean time,copper-containing MSU-s were prepared by the impregnation and direct-insertion methods respectively. TG-DTA,XRD and N2 adsorption-desorption isotherms were employed to characterize the mesoporous materials. The results indicated when using the precursor impregnation procedure to prepare the Cu/MSU-s,the calcination temperature could be lower,so it had ordered hexagonal structure. In addition,the precursor impregnation procedure was easily operated,and this method also can be used to load other metal ions.

摘要: 采用前体浸渍法向具有强水热稳定性的介孔材料MSU-s中引入了铜离子,制得了含Cu的MSU-s。此外,还分别以浸渍法和直接插入法制备了含铜的MSU-s,利用TG-DTA、XRD以及N2吸附等手段对所制备的Cu/MSU-s的微观结构进行了表征分析。研究结果表明:以前体浸渍法制备Cu/MSU-s时,所需焙烧温度较低,且能更好地保持MSU-s的介孔结构。
