Tungsten oxide-supported platinum nanoparticles containing aluminum oxide species (Pt-AlOx/WO3) act as a highly efficient heterogeneous catalyst for the hydrogenolysis of glycerol to 1,3-propanediol without any additives. High 1,3-propanediol selectivity was observed due to the concerted effect of the Pt nanoparticles, aluminum oxide, and tungsten oxide support. The Pt-AlOx,/WO3 catalyst is reusable with maintaining its high catalytic performance.
