000118152 5203_ $$aThe chemo-selective hydrogenolysis of secondary hydroxyls is an important reaction for the production of biomass-derived a, ¿-diols. This is the case for 1, 3-propanediol production from glycerol. Supported Pt-WOx materials are effective catalysts for this transformation, and their activity is often related to the tungsten surface density and Brönsted acidity, although there are discrepancies in this regard. In this work, a series of Pt-WOx/¿-Al2O3 catalysts were prepared by modifying the pH of the solutions used in the active metal impregnation step. The activity–structure relation-ships, together with the results from the addition of in situ titrants, i.e., 2, 6-di-tert-butyl-pyridine or pyridine, helped in elucidating the nature of the bifunctional active sites for the selective production of 1, 3-propanediol. © 2021 by the authors.
