摘要: 本文采用分步交换法首次制得了一种新的层柱材料-氧化铝柱层状镧钛酸盐.应用X射线衍射(XRD)、红外光谱(IR)及透射电子显微镜(TEM)等方法对该新材料进行了表征.结果表明,此材料具有较大的层间距(d=2.05nm,600℃)和较高的热稳定性(700℃).同时,考察了合成条件的改变对该材料性能的影响.

Abstract: A novel pillared-layered material, alumina-pillared lanthanum titanate, was first prepared by a stepwise exchange process and characterized by using XRD, IR and TEM teChniques. The results show that the pillared-layered lanthanum titanate has an interiayer spacing of 2.05nm at 600℃ and a thermal stability over 700℃. The influence of the preparation condition on the properties of the pillared complexes was also studied.
