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 Å2 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.
