General description

Molybdenum hexacarbonyl is a colorless compound that sublimates and decomposes without melting at 150oC. It has an octahedral structure. Inherent sublimation of molybdenum hexacarbonyl permits it to perform as an active liquefaction catalyst. To form a catalyst it is adsorbed on dehydroxylated alumina forming subcarboyls.[1]

Application

Alumina supported molybdenum hexacarbonyl acts as an active catalyst. It is used to synthesize MoO and MoC nanowires by electron beam induced deposition.[2]
