用穆斯堡尔谱学、X射线衍射等方法研究了在多种Al_2O_3载体上的固体-固体表面吸附。结果表明,Eu_2O_3在复合载体Al_2O_3/SiO_2上的固体-固体相互作用和Eu_2O_3在单一载体上分散时的情况有明显差异。用混合模型可成功地解释Eu_2O_3在γ-Al_2O_3或η-Al_2O_3载体表面上的分散。
The solid-solid surface adsorption on a variety of Al 2 O 3 supports was investigated by Mossbauer spectroscopy and X-ray diffraction. The results show that the solid-solid interaction of Eu_2O_3 on the composite carrier Al_2O_3 / SiO_2 and the dispersion of Eu_2O_3 on a single carrier are obviously different. The mixed model can successfully explain the dispersion of Eu 2 O 3 on the surface of γ-Al 2 O 3 or η-Al 2 O 3 support.
