When Does Molybdenum Oxide Equal Molybdenum Hexacarbonyl: Relations Between Heterogeneous and Homogeneous Molybdenum in Syngas Catalysis

摘要

Molybdenum can provide one of the most versatile set of materials for syntheses gas catalysis. In its reduced states (Mo exp 0 -Mo exp +4 ), molybdenum can act as a ''metal'' system yielding mainly hydrocarbon products. In its oxidized state as the trioxide or as a metal molybdate, molybdenum may serve as an alcohol synthesis catalyst or as an alcohol to hydrocarbon conversion system. These oxides can also be used as a support for more typical syngas catalysts. Molybdenum hexacarbonyl undergoes chemistry which can be related to these reactions. These relationships may offer a frontier between molybdenum homogeneous and heterogeneous catalysis. 22 refs., 10 figs. (ERA citation 11:015824)
