Abstract
Catalysts where the support was a nanodisperse solid solution of Gd0.1Ti0.1Zr0.1Ce0.7O2 and the active component was Pd, Pt, or Pd–Pt were obtained. The support was synthesized by co-precipitation with sonication. Palladium and platinum acetylacetonates were used as the precursors. The samples were studied by X-ray powder diffraction (XRD), X-ray fluorescence (XRF), transmission electron microscopy (TEM), and low-temperature nitrogen adsorption. The catalytic activity of the resulting samples in CO oxidation was measured by the flow method. Palladium-containing sample was the most active. The temperature of complete CO oxidation increases in the order Pd > Pd–Pt > Pt. The synthesized catalysts are of interest in detoxification of gas emissions.
