Applications

Molybdenum(VI) oxide is a very promising and stable molybdenum oxide for the electrochromic applications and used as a catalyst in oil industries. It is also used to make metal molybdenum. It has a wide band gap n-type semiconductor with distinctive electrochromic, thermochromic, and photochromic properties. It has been widely investigated as a smart material for catalysis sensors, lubricants, lithium battery, organic solar cells, and display materials. Molybdenum(VI) oxide (MoO3) is employed as an adhesive between enamels and metals.

Notes

It does not react with acids other than hydrofluoric and concentrated sulfuric acids. It reacts with alkali hydroxide solutions to form alkali molybdates.
