Abstract:	Preparation of a MoO3---Al2O3 catalyst with a monolayer of molybdenum oxide on the alumina was possible by adsorbing MoO2(OH)2 at 600 °C from the gas phase. From the amounts of molybdenum adsorbed and the surface areas of the catalysts a characteristic value of 17 A2 was calculated for the area occupied by one MoO3 molecule. Longer times of preparation and high partial pressures of MoO2(OH)2 yielded an aluminum molybdate (Al2O3 · 3MoO3) as evidenced by X-ray analysis. High coverage of the alumina with molybdenum oxide was also possible by adsorbing polymolybdate ions from acid solutions.
