不同形貌氧化铝制备的研究进展

Progress in the Preparation of Alumina with Different Morphologies

氧化铝由于其具有大的比表面、可调的孔容孔径及表面酸性,在工业上作为催化剂载体已经得到广泛的应用。目前对氧化铝的研究多数集中在通过合成条件的控制来调节其孔结构和表面性质,以制备出适合特定催化反应的高性能载体。本文通过介绍不同微观形貌的氧化铝的合成,总结近年来活性氧化铝领域的研究进展,并指明了氧化铝载体今后的研究重点和发展方向。

Abstract： Alumina is widely used as industrial catalyst support due to its high special surface area, tunable pore structure and surface acidity. The research at present is mainly focusing on acquiring highly active catalyst carrier by controlling the porosity and surface property through modulation of the synthesis procedure. Researches on synthesizing of transition alumina with various microstructures are reviewed, then final research orientations in this area are also suggested for further investigation.
