Fig. S3 Toluene conversion over MnO2/LaMnO3 with the toluene concentration at 500 ppm, 1000 ppm and 1500 ppm. Reaction conditions: 0.10 g catalyst, 20% O2, balance N2, WHSV = 40000 mL g-1 h-1.Fig. S4. Effects of H2O on the activity of the MnO2/LaMnO3 at 240 °C. Reaction conditions: 0.10 g catalyst, 1000 ppm toluene, 20% O2, 2% H2O, balance N2, WHSV = 40000 mL g-1 h-1.Table S1 The results from SEM-EDS analyses of the three samples.
