采用XRD和XPS研究了MoO2(acac)2配合物热扩散制备的钼-氧化铝、钼-硅-氧化铝和钼-硅体系的性能。在较大的Mo负载范围内，测定了催化剂在丙烯复分解中的活性。当Mo含量较低时，钼-硅-氧化铝催化剂的比活性远高于其他两种体系，而当Mo含量较高时，钼-氧化铝催化剂的效率最高。
The properties of molybdena-alumina, molybdena-silica-alumina and molybdena-silica systems prepared by thermal spreading of MoO2(acac)2complex were investigated with XRD and XPS. The activity of the catalysts in propene metathesis was measured for a wide range of Mo loadings. For the low Mo content, the specific activity of the molybdena-silica-alumina catalyst is much higher than for both other systems, while for the high Mo loadings, the molybdena-alumina catalyst exhibits the highest efficiency.
