We present here a simple sonochemical synthesis of nanostructured molybdenum carbide from the ultrasonic irradiation of molybdenum hexacarbonyl. In addition, we have examined the catalytic activity and selectivity of these materials for the dehydrogenation of alkanes. In conclusion, sonochemical decomposition of molybdenum hexacarbonyl produces nanometer-sized powders of face-centered cubic molybdenum carbide. The material consists of highly porous aggregates of 2 nm sized particles with a very high total surface area. Mo{sub 2}C generated sonochemically is an excellent dehydrogenation catalyst with selectivity and activity comparable to those of Pt. 20 refs., 3 figs.
