A series of silica supported rhodium-nickel catalysts with varying amounts of both components have been characterized by temperature-programmed reduction, X-Ray diffraction, hydrogen chemisorption and tested in the CO2 reforming of methane reaction. The reduction of bimetallic catalysts occurs at lower temperatures, as compared to a monometallic nickel catalyst, showing that rhodium and nickel are in close interaction. XRD results Indicate the formation of Ni/Rh alloys in the process of bimetallic catalysts reduction. All catalysts under study show high activity in the reaction of CO2 reforming of methane, but the significant improvement in the stability is characteristic for rhodium and bimetallic catalysts.
