Interaction between ruthenium and molybdenum in RuMo/Al 2O 3 catalysts

RuMo/Al 2O 3 catalysts with various molybdenum loadings (0.15–0.6 wt.-%) and 0.6wt.-% ruthenium were prepared and characterized by hydrogen and carbon monoxide chemisorption. n-Hexane hydrogenolysis and cyclohexane dehydrogenation were performed over the reduced catalysts. Cyclohexene dehydrogenatio...

Summary:RuMo/Al 2O 3 catalysts with various molybdenum loadings (0.15–0.6 wt.-%) and 0.6wt.-% ruthenium were prepared and characterized by hydrogen and carbon monoxide chemisorption. n-Hexane hydrogenolysis and cyclohexane dehydrogenation were performed over the reduced catalysts. Cyclohexene dehydrogenation was also carried out over the sulfided catalysts. The results suggest an electron transfer from molybdenum to ruthenium sites.
