What is Molybdenum Trioxide?
Molybdenum trioxide is a chemical compound with the formula MoO3. This compound is produced on the largest scale of any molybdenum compound. It is an intermediate in the production of molybdenum metal. It is also an important industrial catalyst. Molybdenum trioxide occurs as the rare mineral molybdite.
Preparation and principal reactions
MoO3 is produced industrially by roasting molybdenum disulfide, the chief ore of molybdenum:
- 2 MoS2 + 7 O2 → 2 MoO3 + 4 SO2
The laboratory synthesis of the dihydrate entails acidification of aqueous solutions of sodium molybdate with perchloric acid:
- Na2MoO4 + H2O + 2 HClO4 → MoO3(H2O)2 + 2 NaClO4
The dihydrate loses water readily to give the monohydrate. Both are bright yellow in colour.
Molybdenum trioxide dissolves slightly in water to give “molybdic acid”. In the base, it dissolves to afford the molybdate anion.
Uses of Molybdenum Trioxide
Molybdenum trioxide is used to manufacture molybdenum metal, which serves as an additive to steel and corrosion-resistant alloys. The relevant conversion entails treatment of MoO3 with hydrogen at elevated temperatures:
- MoO3 + 3 H2 → Mo + 3 H2O
It is also a component of the co-catalyst used in the industrial production of acrylonitrile by the oxidation of propene and ammonia.
Because of its layered structure and the ease of the Mo(VI)/Mo(V) coupling, MoO3 is of interest in electrochemical devices and displays. Molybdenum trioxide has also been suggested as a potential anti-microbial agent, e.g., in polymers. In contact with water, it forms H+ ions that can kill bacteria effectively.
