| Abstract: |
Highlights: [•] Rh, Pt, Pd and Au on ZnO were tested for glycerol catalytic transformation into 1,2-PDO and acetol. [•] The synthetic approach (microemulsion) allowed us to obtain similar particle sizes for Pt, Pd and Rh. [•] Glycerol conversion order followed the sequence Rh>Pt>Pd (Au was inactive under our experimental conditions). [•] Higher activity and selectivity for systems synthesized through microemulsion as compared to deposition–precipitation method. [•] The metal seems to participate both in the hydrogenation of acetol to 1,2-PDO and in the previous dehydration step of glycerol to acetol. [Copyright &y& Elsevier] |
