Insight into the Influence of WOx‐Support Interaction over Pt/W/SiZr Catalysts on 1,3‐Propanediol Synthesis from Glycerol

Abstract For Pt‐WO x ‐based catalysts, researchers pay much attention to study the influence of Pt‐WO x interaction on glycerol hydrogenolysis, ignoring the interaction between WO x and support. Herein, four Pt/W/SiZr‐T catalysts with different surface hydroxyl groups on support are prepared and characterized. The results show that bibridged (OH II ) and tribridged hydroxyl groups (OH III ) on SiZr‐T supports could react with WO x species through forming Zr−O−W bands and retard the agglomeration of WO x species. The highly dispersed WO x species and Zr−O−W bands are the origination of inherent and in‐situ generated Brønsted acid, which are beneficial for 1,3‐propanediol synthesis. As a result, Pt/W/SiZr‐70 exhibits outstanding performance due to abundant OH II and OH III on SiZr‐70. The initial space time yield of 1,3‐propanediol on Pt/W/SiZr‐70 reaches 2.280 g 1,3‐PDO ⋅ g cat −1 ⋅ h −1 , the highest among reported results. This r esearch reveals the role of WO x ‐support interaction on glycerol hydrogenolysis and provides a new direction to design Pt‐WO x ‐based catalysts for selective hydrogenation reactions.
