Abstract in another language
Zeolites find application in gas sensors as catalyst or molecular filter material to modify the gas composition in front of the sensitive element, or as gas-sensitive material. For zeolites as gas-sensitive material, mechanical (mass sensitive), optical, and electrical sensing principles are known. The present paper deals with new electrical gas sensor mechanisms based on electrical interface phenomena in zeolites. Other electrical gas sensing principles of zeolites are based on changes of capacitance or of ionic conductivity upon gas sorption for detection of alkanes, alcohols, H2O, or NH3. Different from these mechanisms, which involve the detection of changes of electric properties of the zeolite volume, the mechanisms of the response of junctions between zeolites and electron conducting materials to gas atmospheres is presently less well understood. Only a few similar examples are found in the literature, including a potentiometric H2 sensor using HY and NH4Y zeolites and a CO2 sensor.
