摘要
对负载型Ｆｅ２Ｏ３－Ｌａ２Ｏ３－γ－Ａｌ２Ｏ３的ＸＲＤ、ＭＢＳ等方法的研究表明，Ｌａ２Ｏ３对γ－Ａｌ２Ｏ３的改性，提高了载体的热稳定性，增强了活性组份同载体的相互作用，提高了活性组份在载体表面的分散能力。
X--ray diffraction(XRD) and Mssbauer spectroscopy(MBS) have been used to study the supported Fe2O3-La2O3-γ-Al2O3 catalyst. The results show that modification of the carrierγ-Al2O3 by La2O3 reinforces the thermostability of the support and catalyst, intensifies the interaction between active component and support and enhances the dispersity of active component on the carrier.
