	abstract = {<p>Bifunctional Pt/WO3/zirconium phosphate catalyzes the liquid-phase hydrogenolysis of glycerol in an aqueous medium. H-1 NMR spectroscopy (solvent suppression pulse program) is employed to monitor this reaction. Propanediols (1,3 + 1,2-PDO) formed as the major product along with propanols (1- and 2-POs) as the minor product. A synergistic enhancement in glycerol conversion and selectivity to 1,3-PDO was observed when both Pt and WO3 were present in the catalyst. A volcano-shape variation of catalytic activity with W content was observed. A catalyst with 8 wt\% W and 1 wt\% Pt exhibited the highest selective hydrogenolysis performance (glycerol conversion = 92.3\% and total PDOs selectivity = 45.9\% and 1,3-PDO selectivity = 20.8\% at 200 degrees C). Dispersed Pt in contact with polytungstate-type WO3 species was found to be the active catalytic site. H-1 NMR spectroscopy is demonstrated as an attractive technique to quantify the products of a glycerol hydrogenolysis reaction.</p>},
