| 摘 要： | 采用XPS和XRD方法，测定了MoO3在未经改性的MCM－41及用Al2O3和TiO2改性后的MCM－41上的单层分散阈值，发现，MoO3在用Al2O3和TiO2改性后的MCM－41上的单层分散阈值比未经改性的MCM－41上的要提高三分之二。另外，借助MoO3/MCM-41、MoO3/Al2O3-MCM-41、MoO3/TiO2-MCM-41系列样品的比表面积和孔分布测定，研究了MoO3在未经改性的MCM－41及用Al2O3和TiO2改性后的MCM－41上的分散状况。

| Abstract: | XPS and XRD methods were used to determine the monolayer dispersion capacity of MoO\-3 on the surface of unmodified MCM\|41, and Al\-2O\-3, TiO\-2 modified MCM\|41 as well. It is found that the monolayer dispersion capacity of MoO\-3 on the surface of Al\-2O\-3, TiO\-2 modified MCM\|41 is two thirds greater than that on unmodified MCM\|41. Besides, the dispersity of MoO\-3 on the surface of unmodified MCM\|41 and Al\-2O\-3, TiO\-2 modified MCM\|41 was also studied by measuring the BET surface area and pore size distributions of MoO\-3/MCM\|41, and MoO\-3/Al\-2O\-3\|MCM\|41, MoO\-3/TiO\-2\|MCM\|41 samples. |
