Molybdenum trioxide is 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.
Chemical formula：MoO3
Molar mass：143.95 g·mol−1
Appearance:yellow or light blue solid
Odor:odorless
Density:4.70 g/cm3
Melting point:802 °C (1,476 °F; 1,075 K)
Boiling point:1,155 °C (2,111 °F; 1,428 K)(sublimes)
Solubility in water:1.066 g/L (18 °C)/4.90 g/L (28 °C)/20.55 g/L (70 °C)
Application
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.
