Abstract

Selective hydrocarbon gas sensors were obtained by covering interdigital electrodes with combinations of chromium(III)oxide and Pt-doped ZSM-5 zeolite thick-films. A highly sensitive and selective sensor was achieved by a Pt-ZSM-5 film on Au electrodes coated with Cr2O3. Presumably this can be attributed to a novel sensing effect at the interface between Cr2O3 and zeolite.
