3.3.4 Zeolite Modified Gas Sensors For Environmental Monitoring

A. Afonja, I. P. Parkin & R. Binions
Metal oxide semiconductor gas sensors with zeolite over layers or admixtures have been prepared and used to investigate the detection of a number of environmentally important gases. The results show the sensors have consistent and repeatable gas response behavior. Additional testing indicated that the sensors gave good discrimination between gases across an array of sensors.
