Pure nanocrystalline TiO2 thick films have been prepared by doctor blade technique on glass substrate. The nanostructural properties of the powder as well as thick films and gas sensing performance of the TiO2 thick films towards hydrogen, ethanol and ammonia gases have been studied and presented here. The experimental results revealed that these nanostructured TiO2 films are sensitive to different gases such as hydrogen, ammonia and ethanol at low operating temperature close to 55–65 °C. The TiO2 film shows highest sensitivity towards ammonia gas as compared to hydrogen and ethanol.
