Abstract

Highly redispersible anatase nanoparticles were prepared by a novel sol–gel based hydrothermal process for gas sensing applications. Thin titania films composed of nanoparticles were deposited on Au interdigital electrodes by dip-coating, annealed and tested in a gas test bench at 350 °C. The anatase films showed a very high sensitivity towards ammonia and no cross interference by CO2, O2 and C3H8. To classify the sensor as an ammonia gas sensor, a comparison with other sensor designs from literature has been performed.
