Abstract

Platinium-Paladium bimetallic nanoparticles (Ptx-Pd(1-x)) supported on amorphous silica (SiO2) were prepared by wetness impregnation techniques at different concentrations of Pt and Pd 1 metallic wt.%. Physical properties like microstructure were studied by X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM) and chemical properties were used to establish the activity of these nanoparticles supported in the cyclohexene isomerization reaction and its specific area by physisorption (BET). Influence of the chemical composition and particle size on the cyclohexene isomerization reaction was also studied.
