Applications:

1. Catalyst:

   • Sulfuric Acid Production: V₂O₅ is an essential catalyst in the contact process for the oxidation of sulfur dioxide (SO₂) to sulfur trioxide (SO₃), which is a key step in the industrial production of sulfuric acid.
   • Selective Catalytic Reduction (SCR): It is used to reduce nitrogen oxides (NOx) in industrial emissions to nitrogen (N₂) and water, aiding in pollution control.
   • Oxidation Reactions: It is also used as a catalyst in various organic oxidation reactions, including the production of phthalic anhydride.

2. Ceramics and Glass:

   • V₂O₅ is used as a colorant and as a fluxing agent in ceramics and glass production. It can impart a yellow or orange color to glazes and is also used to improve the chemical durability of glass.

3. Batteries:

   • Vanadium pentoxide is used in some types of lithium-ion batteries and vanadium redox flow batteries due to its high energy density and electrochemical properties.

4. Pigments:

   • Due to its vibrant color, V₂O₅ is sometimes used in the production of pigments.

Storage:

Vanadium pentoxide should be stored in a cool, dry place, away from incompatible materials such as strong acids and reducing agents, to prevent unwanted reactions. Containers should be tightly closed and properly labeled.
