Abstract

Rhenium-oxide-modified supported iridium nanoparticles on silica catalyzes direct hydrogenolysis of glycerol to 1,3-propanediol in an aqueous media. The selectivity to 1,3-propanediol at an initial stage reaches 67%. The yield of 1,3-propanediol reaches 38% at 81% conversion of glycerol. The characterization of catalyst shows that oxidized Re clusters are formed on Ir metal particles. The synergy between Ir metal and ReOx clusters enables the catalytic activity.
