ABSTRACT:

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)
