Abstract
Abstract The use of multi-walled carbon nanotubes as support for Au nanoparticles results in the preferential chemoselective orientation of glycerol oxidation towards the reaction of the secondary alcohol function; a dihydroxyacetone selectivity of 60% was obtained in combination with a high activity, which is an interesting result reported here for the first time. On the other hand, an activated carbon supported gold catalyst, prepared under the same conditions, with similar metal loading and average particle size, promotes the formation of glyceric acid. This suggests the importance of support textural properties on the gold catalytic performance in glycerol selective oxidation.
