Abstract
The effect of Pd, Ru and Rh doping on microstructure, electrical, and gas sensor properties of nanocrystalline tin dioxide films is studied. SnO 2 and SnO 2(M) (M=Pd, Ru, Rh) films of 0.9–1-μm thickness and a doping metal content of 0.07–1.6 at.% are synthesized by aerosol pyrolysis. Studies at 50–400 °C of the evolution of conductivity of noble metal-doped tin dioxide films put in contact with gas mixtures containing small amounts of CO and NO 2 give evidence of strong similarities of the interaction mechanisms. Correlations between the electrical response and oxygen affinity of noble metal clusters were found.
