Abstract

The nanodisperse Au/Cе_0.72Zr_0.18Pr_0.1O₂ catalysts for low-temperature oxidation of carbon monoxide were synthesized. The compounds were identified by XRD, XPS, TEM, ISP-MS, and gas chromatography. The samples containing gold nanoparticles obtained by radiation chemical reduction in reverse micellar dispersion exhibited higher activity than the catalysts obtained by deposition-precipitation (DP) despite the higher content of the active component.
