General description

Titanium(IV) oxide is a semiconductorphotocatalyst with a band gap of 3.0 eV. It is widely used in the field of photovoltaics,sensors, and environmental remediation due to its unique properties such ashigh reactivity, stability against photocorrosion, and ease of furtherfunctionalization.

Application

Titanium(IV) oxide (TiO2) and functionalized TiO2 can be used as a photocatalyst for overall water-splitting reactions and photocatalytic hydrogen evolution.

Rutile titanium(IV) oxide exhibit a high dielectric constant and can be used as a component in low-temperature cofired ceramics (LTCC) or as a filler in organic-inorganic composites.

Au/rutileTiO2 can be used as a photocatalyst for selective aerobic oxidation of amines to corresponding imines.

Features and Benefits

Possesses improved photocatalytic activity.
