摘要
综述了介孔氧化铝的金属、非金属改性以及复合改性研究,金属改性包括锆改性、镍改性、钛改性以及铈改性,金属改性主要改善介孔氧化铝的热稳定性及表面酸性。非金属改性包括硼改性、磷改性以及硅改性,主要调变介孔氧化铝的表面酸性。复合改性主要结合各元素的性能,并引出新的特征。指出改性机理的探索和复合改性将成为介孔氧化铝改性的主要研究方向。
The research progresses in metal, non-metal and composite modifications of mesoporous alumina are introduced. The metal modification could mainly improve the thermal stability and surface acidity of mesoporous alumina, including zirconium, nickel, titanium and cerium modifications. The non-metal modification adjusts mainly the surface acidity of mesoporous alumina, including boron, phosphorus and silicon modifications. The composite modification mainly combines the properties of different ingredients, and leads to new features. It is pointed out that the exploration of modification mechanism and the composite modification will be the main research directions in the future for modification of mesoporous alumina.
