Sensitive Material

In literature, many papers describe the applications of semiconductor as sensitive material in sensor field. The gas sensor using tin oxide requires a strictly controlled high operating temperature in order to detect both reducing and oxidizing gases. The semiconductor nanoparticles, with their high specific surface area, increase the gas sensing performance. The originality of this work is to valorize the nanoparticle of metal oxide like SnO2, TiO2 obtained by microwave thermohydrolysis synthesis, using a gas sensing microwave transduction. The present synthesis is to prepare metal oxide nanocrystalline powder with a high surface area by microwave-induced thermohydrolysis. We propose to study the influence of the metal oxide nanoparticle, as a sensitive layer, in gas sensing measurement. The pollutant is added into an argon flow (dynamic regim). This work highlights a specific sensor response to each ammonia concentration at room temperature. It shows a quasi-linear relationship between the set of points of the real part of the response and the ammonia concentration. The authors are currently working on these issues as well as the interaction mechanism between adsorbed gas molecules and metal oxide films.
