Abstract:Glycerol has been selectively converted into 1,2-propandiol in the presence of dihydrogen and heterogeneous Pt-based catalysts. These latter catalysts consist of small-size Pt-nanoparticles (NPs) (i.e. 1.0-1.5 nm,) obtained by a metal vapor synthesis, supported on different carbonaceous supports which differ mainly in surface area and surface polarity. Catalytic data combined with microscopic (i.e. TEM investigations of the supported Pt-NPs after catalysis) evidences showed a good correlation between the catalytic activity and chemoselectivity of the Pt-NPs and the NP-stabilizing property of the carbonaceous supports.
