The selectivity to p-CAN as a function of conversion against various parictie sizes of Pt over Pt/CeO2 (a), Pt/γ-Al2O3 (b), Pt/TiO2 (e), Pt/La2O3 (f) and Pt/θ-Al2O3 (g). c Selectivity of p-CAN at nearly full converison of p-CNB over Pt/CeO2 and Pt/γ-Al2O3 with various parictie sizes of Pt. d The ∆Sel of p-CAN between Pt/CeO2 and Pt/γ-Al2O3 with similar particle size. h The selectivity of p-CAN against the fraction of Pt0 over different catalyst with various parictie sizes of Pt. The special marks in figures (c) and (d) represents the theoretical critical size of Pt. Reaction conditions: 10 mL toluene, 1 MPa H2, 45 °C, 0.5 mmol p-CNB, Pt/p-CNB: 10 wt‰.
