研究了MoO2(acac)2配合物锚定法制备的钼氧化铝催化剂的性能和分解活性，并与传统浸渍法制备的钼氧化铝体系进行了比较。在锚定催化剂的情况下，XPS分析表明，与浸渍催化剂相比，锚定催化剂在氧化铝上的分散性更好，并且在丙烯的分解中比浸渍催化剂更活跃。用四甲基锡处理过的催化剂也是如此。
The properties and metathesis activity of molybdena-alumina catalysts prepared by anchoring of MoO2(acac)2complex were investigated and compared with the traditionally-impregnated molybdena-alumina systems. In the case of the anchored catalysts, XPS analysis indicates better dispersion of molybdenum species on alumina, compared to the impregnated ones, as well as the anchored catalysts are more active then the impregnated ones in propene metathesis. The last statement is also true for the catalysts treated with tetramethyltin.
