Abstract:
The possibility of using ruthenium in the composition of palladium–rhodium catalysts used to neutralize the exhaust gases of vehicles with gasoline engines was investigated. The thermolysis of a supported precursor in oxidizing and reducing atmospheres led to the formation of samples with different initial catalytic activity. The stability of trimetallic systems was compared under conditions of prompt thermal aging with that of reference samples of similar chemical composition but obtained by mechanical mixing of monometallic catalysts. The results obtained allowed us to conclude that the alloy nanoparticles were more stable, and the thermolysis of the precursor in a reducing atmosphere contributed to a higher initial activity of the catalyst in the oxidation of CO. According to the X-ray photoelectron spectroscopy data, the high thermal stability of trimetallic catalysts was due to a constant ratio between metals on the support surface in the course of the catalytic reaction.
