Rh double-oxide compound (MnRh2O4) was formed by air calcination treatment of manganese oxide-promoted Rh/SiO2 catalyst at 900 °C, and characterized by Rietveld analysis of the X-ray diffraction pattern. The MnRh2O4 particles on SiO2 were reduced to smaller Rh metal particles by H2 treatment at 300 °C, and this catalyst system exhibited a strong Rh-MnOx interaction behavior in catalytic studies of ethane hydrogenolysis and cyclohexane dehydrogenation reactions.
