Mechanistic insights into acid-affected hydrogenolysis of glycerol to 1,3-propanediol over an Ir–Re/SiO2 catalyst

Abstract

Glycerol hydrogenolysis to 1,3-propanediol is identified to follow the dehydration-hydrogenation pathway with the rate-determining step (RDS) of H* + OH* → H2O* over an IrRe catalyst. The positive effects of solid acids are elucidated to originate from the reduced energy barrier of the RDS by H protons, while the negative ones of liquid acids are from excessively strong adsorption of anions.
