摘要/Abstract

摘要：

以三嵌段共聚物作为结构导向剂,采用水热法合成了片状和棒状介孔氧化铝,采用X射线衍射仪、场发射透射电子显微镜、低温氮气吸脱附实验对合成的介孔氧化铝的晶相、形貌和介孔结构进行表征。研究结果表明,三嵌段共聚物的引入能够有效调控氧化铝的形貌、介孔结构以及孔参数。三嵌段共聚物在氧化铝前驱体表面的吸附诱导了晶体的取向生长,并最终形成了棒状氧化铝。

Abstract:

In this study, sheet-like and rod-shaped mesoporous aluminas were synthesized with a triblock copolymer as the structure-directing agent via hydrothermal method. X-ray diffraction, transmission electronic microscopy and nitrogen adsorption and desorption were performed to determine the crystalline phase, morphology and pore structure of the aluminas. It was found that the morphologies, mesostructures and pore parameters of aluminas can be altered by the introduction of the triblock copolymer. The adsorption of the triblock copolymer on the surface of the alumina gels induced the oriented growth of the crystallines, resulting in the formation of final aluminas nanorods.

Key words: alumina, mesoporous, hydrothermal, structure-directing, nanorod
