Nanoparticulate catalysts M/Ce0.72Zr0.18Pr0.1O2, where M - Pt, Pd, Ru at 0.5; 1.0 and 2.0 weight%, for diesel exhaust soot afterburning in a ""weak"" contact were synthesized. Structural, textural and catalytic properties of the samples were studied using EDX, X-ray synchrotron diffraction, XANES, EXAFS, TEM, low-temperature nitrogen adsorption and TG-DSC. It is shown that in the process of impregnating of platinum metals on the surface of the support Ce0.72Zr0.18Pr0.1O2, metal-support interaction occurs and increases in a line Pt → Pd → Ru. Ruthenium-containing catalysts are the most active in the soot afterburning, not only due to the nature of the supported component, but relatively faint metal-support interaction as compared with platinum and palladium samples. For them it is characterized the reduction of start oxidation temperature on 190 °C and lowering the temperature of complete oxidation approx. on 120 °C compared with the same parameters for the support without platinum. Due to the high activity of 0.5%Ru/Ce0.72Zr0.18Pr0.1O2 the opportunity for effective cleaning of diesel soot emissions are created by using relatively small amounts of the precious metal, which will reduce the cost of catalytic converters of diesel emissions.
