The catalytic properties of supported Cu/SBA-15 catalysts prepared by the ion-exchange method were investigated for the hydrogenolysis
of glycerol in a fixed-bed tubular reactor. The Cu/SBA-15 catalyst performed higher selectivity to 1,2-propanediol and high
stability. We propose that the larger specific surface area and the ordered mesoporous channels of SBA-15 may play important
roles in stabilizing highly dispersed copper species, and forming an active and durable catalyst for the title reaction.
