Aqueous phase hydrodeoxygenation of polyols over Pd/WO3-ZrO2: Role of Pd-WO3 interaction and hydrodeoxygenation pathway

- Presence of both Pd and WO3 is crucial for aqueous phase HDO of polyols.
- Strong interaction between Pd and WO3 leads to tuned acidity and hydrogenation activity.
- Aqueous phase HDO of polyols follows the dehydration-hydrogenation pathway.
- Dehydration is in equilibrium of the hydration on Pd/WO3-ZrO2.
- Hydrogenation of dehydration product leads to the selective hydrodeoxygenation.
