Selective conversion of glycerol to 1,3-propanediol using Pt-sulfated zirconia

Pt-deposited sulfated zirconia was used as a catalyst for the selective hydrogenolysis of glycerol to 1,3-propanediol. The Brønsted acid sites on the catalyst, which were promoted by hydrogen spillover on platinum, were more advantageous for producing 1,3-propanediol than 1,2-propanediol.
