A novel Pd/C-catalyzed conversion of glucose to 1,2-propanediol by water splitting with Zn

A novel Pd/C-catalysed conversion of glucose to 1,2-propanediol by water splitting with Zn was proposed. The yield of 1,2-akanediols reached 48%, mainly including 1,2-propanediol (33.3%), the reported highest yield from glucose. Water, as a solvent, provides an in situ and active hydrogen source. The formed ZnO acts as a catalyst with Pd/C.
