General description

Titanium(IV) oxide is a semiconductor with asmaller band gap of 3.0 eV. Among the polymorphs of TiO2, rutile isthe most stable phase in wide temperature and pressure ranges. It is widelyused as a photocatalyst in electrochemical water-splitting reactions and alsofinds application in the field of photovoltaics, sensors, and environmentalremediation.

Application

Titanium(IV) oxide can be used as a photocatalyst for an overall water-splitting reaction. It can also be used as an efficient catalyst for phenol degradation under visible light.

Features and Benefits

  • Chemical stability
  • Non-toxicity
  • Excellent stability against photocorrosion
  • Ease of further functionalization
Possesses improved photocatalytic activity.
