Ru:Ag alumina supported bimetallic system was prepared by co-impregnation method and characterized ruing X-ray diffraction technique. On the basis of experimental data the intensity lines corresponding in Ag, Al, Ru, RuO with Ag occurring at the surface of Ru as island were found The shift in the angle of diffraction and de change in the intensity of the Ru peaks samples indicates the presence of particles greater than 5 mo dispersed randomly on the catalyst surface. At 0.02% Ru:Ag atomic ratios no XRD intensity Line of Ag was found indicating that Ag is present on the surface in the form of very small particles. The metal dispersion calculated from the XRD data reveals geometric effect of Ag rather than any Ru-Ag electronic interaction.
