Titanyl sulfate

Titanyl sulfate is the inorganic compound with the formula TiOSO4. It is a white solid that forms by treatment of titanium dioxide with fuming sulfuric acid. Titanyl sulfate hydrolyzes to a gel of hydrated titanium dioxide.

It is used as a precursor to synthesize a wide range of titanium dioxide (TiO2) photocatalysts.

It can also be used in the synthesis of freeze dried titanium foams, and WO3-loaded TiO2 photocatalyst applicable for the oxidation of trans-ferulic acid to vanillin.

Titanyl sulfate is furthermore used as a detection reagent for hydrogen peroxide and titanium, since the intense orange-yellow colored peroxotitanyl ion (TiO2) 2+ is formed when it is present. This detection is very sensitive and traces of hydrogen peroxide can already be detected.

It is also an intermediate in the titanium dioxide sulphate process.
