Detection of VOCs by microwave transduction using dealuminated faujasite DAY zeolites as gas sensitive materials

摘要

The gas sensing is an environmental topic representing a strong interest for this century. Whatever the purpose, industrial emissions control or indoor quality air supervision, the challenge remains to produce effective low costs detection systems adapted to the atmospheric conditions. This study focuses on the estimation of the microwaves transduction technique viability for the toluene detection. Sensors are based on zeolites powders, deposited on coplanar structures adapted to the microwave frequency range. We shall apply to explain the principles of the microwave transduction before approaching the conception of the sensors, the measurement protocol and the obtained results.
