The Contact Process for sulfuric acid production uses vanadium(V) oxide, V₂O₅, as a catalyst for the oxidation of sulfur dioxide (SO₂) to sulfur trioxide (SO₃). This is a crucial step in the industrial synthesis of H₂SO₄.

$$2{\mathrm{SO}}_2(g)+{\mathrm{O}}_2(g)\stackrel{{\mathrm{V}}_2{\mathrm{O}}_5}{\to }2{\mathrm{SO}}_3(g)$$
