摘要
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. © All right reserved.
