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。

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.
