Controlling the selectivity of supported Ru nanoparticles during glycerol hydrogenolysis: C-O vs C-C cleavage - data

This data set supplements the data presented in the publication "Controlling the selectivity of supported Ru nanoparticles during glycerol hydrogenolysis: C-O vs C-C cleavage". Here we submit TGA, XPS meta data. Controlling the selectivity of a reaction by rational designing of catalyst is an exciting and an important topic in catalysis research. We report a strategy to control the selectivity during the aqueous phase hydrogenolysis of glycerol using gaseous H₂. Ru/TiO₂ is an active catalyst for the hydrogenolysis of glycerol, however it promotes the breaking of C-C bonds during this reaction resulting in large quantities of C2 and C1 products. On the other hand, Pd/TiO₂ and Pt/TiO₂ catalysts are very selective for the hydrogenolysis of C-O bond in glycerol producing mainly C3 products (1,2 and 1,3 propanediols), however they are much less active compared to the Ru catalysts. In this article, we report that by combining Ru and Pt or Pd in a bimetallic nanoparticle, we can design new catalysts that are both active (property of Ru) and selective for C-O hydrogenolysis (property of Pd or Pt). A physical of mixture of two monometallic catalysts does not show this enhanced selectivity for C-O hydrogenolysis, proving that intimate mixing of the two metals in a nanoparticle is crucial to tune the selectivity.
