Performances of Titania-Supported Ru-Based Bimetallic Catalysts in Glycerol Hydrogenolysis Reaction

Abstract:

Preliminary studies on the hydrogenolysis of glycerol over the titania-supported Ru-based bimetallic catalysts (Ru-Fe/TiO₂, Ru-Co/TiO₂, Ru-Ni/TiO₂ and Ru-Cu/TiO₂) were reported. The introduction of a second transition metal can obviously increase the selectivity to 1,2-propanediol of the Ru catalysts, but a deactivation effect was also found. The catalytic performances of the Ru-based bimetallic catalysts were discussed with a proposed reaction mechanism. The addition of Fe, Co, Ni or Cu enables the Ru-based catalysts to favor the dehydration route over the retro-aldolization route in the reaction process.
