Gas-sensing properties of nanostructured TiO 2 –xZrO 2 thin films obtained by the sol–gel method

TiO2–xZrO2 films and powders were synthesized by sol–gel technique. TiO2–xZrO2 (x = 0–20 mol.%) possess anatase structure. A film with x = 40% has zirconium titanate structure, a film with x = 50% is amorphous. Anatase-structured films exhibit a high reproducible response to О2. The film with x = 10% possesses the best response to O2.
