Figure 6. (A) Schematic illustration of the preparation of Pt₁Cu SAA catalysts; (B) conversion versus reaction time, (C) product selectivity, and (D) TOF value towards glycerol hydrogenolysis to 1,2-PDO over the Pt₁Cu SAA and monometallic catalysts (Pt/MMO and Cu/MMO); (E) Reaction mechanism of hydrogenolysis of glycerol to 1,2-PDO for the PtCu-SAA catalysts.
