T. Paryjczak et al., STUDIES ON RELATIONSHIP BETWEEN CATALYTIC ACTIVITY OF METAL SNO2 SYSTEMS AND THEIR ACTIVITY AS GAS SENSORS, Przemysl Chemiczny, 72(3), 1993, pp. 106-108
Activity of following catalysts: Pt/SnO2, Pd/SnO2, Ag/SnO2, Cu/SnO2, a
nd Ni/SnO2 have been tested in the reaction of CH4, CO, and H-2 oxidat
ion. Gas sensors made of these catalysts have been found to deactivate
pretty fast at temperatures from 293 K to 793 K. Deactivation for var
ious sensors did not occur at the same time.
