Anchored and impregnated molybdena-alumina metathesis catalysts—a comparative study

The properties and metathesis activity of molybdena-alumina catalysts prepared by anchoring of MoO 2(acac) 2 complex were investigated and compared with the traditionally-impregnated molybdena-alumina systems. In the case of the anchored catalysts, XPS analysis indicates better dispersion of molybde...

Description
Summary:The properties and metathesis activity of molybdena-alumina catalysts prepared by anchoring of MoO 2(acac) 2 complex 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.
