This research develops a bimetallic catalyst that enhances propanediol production from glycerol under acidic conditions, suggesting a method without external hydrogen.
In acidic conditions, hydrogenolysis occurs by consecutive glycerol dehydration to acetol and hydrogenation to 1,2-PDO. The glycerol dehydrogenate to glyceraldehyde, followed by dehydration to 2-hydroxypropenal and hydrogenation to 1,2-PDO.
