Abstract: Highlights: [•] The relationship between the reaction rate and the Pt-Re particle size is found to follow a volcanic curve. [•] Smaller sized Pt-Re/CNTs catalysts lead to increased activity together with enhanced coking behavior. [•] Larger sized Pt-Re/CNTs catalysts favor the cleavage of the secondary C–O bond for both glycerol and 1,2-propanediol. [•] The dependence of reaction pathway on particle size is correlated.
