Abstract

The study of catalysts based on a Ce0.72Zr0.18Pr0.1O2 solid solution with Pt, Pd, and Ru supported from acetylacetonate precursors showed their high activity in the processes of CO and methane oxidation. Transmission electron microscopy, X-ray absorption spectroscopy, and X-ray photoelectron spectroscopy were used for determining the nature of the active sites of the catalysts. The metal-support interaction effect, which increased in the order Ru < Pd < Pt, was found, and a relationship between the intensity of this interaction and the catalytic action was established.
