Fig. 12. Re-use testing of the AuPt/LaMnO3 catalyst. Black fill = glycerol conversion; black dashed = glyceric acid selectivity, red fill = tartronic acid selectivity; green fill = C–C scission selectivity and blue fill = lactic acid selectivity. Conditions: glycerol 0.3 M in water, 4 : 1 NaOH : glycerol, glycerol : metal = 1000, 3 bar O2, temperature = 100 °C.
