Molybdenum(VI) oxide (MoO3) is an acidic metal(VI) oxide. It is widely employed in selective oxidation reactions. Its temperature-programmed reduction has been reported. Kinetics and mechanism of its reduction in the presence of hydrogen, propene, butene-1 and CO has been investigated. It is reduced to metal upon reaction with hydrogen at high temperatures.
