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 17Å2 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.
