An optimized route for the preparation of well dispersed supported ruthenium catalysts

Abstract

The preparation of ceria and ceria–zirconia supported ruthenium catalysts was optimized in order to get well-dispersed metal particles. The influence of the preparation method and the treatment conditions on the final morphology of the catalyst was investigated. Ceria-supported catalysts, prepared by incipient wetness impregnation under ultrasound and further treated under pure hydrogen, were shown to have an optimal metal dispersion. In fact, H2 chemisorption results and TEM observations demonstrated a large increase in the metal accessibility when impregnation was carried out with ultrasound assistance. Ceria-supported ruthenium catalysts with dispersion as high as 60% were prepared.
