Fig. 2: Propane oxidation over (PtNiCo)core(PtNiOCoO)surface catalyst.
From: Surface oxygenation of multicomponent nanoparticles toward active and stable oxidation catalysts
Propane conversion over the ternary catalyst derived from PtNiCo–PtNiOCoO/Al2O3 (n = 42, m = 39, 1.0 wt%, black) and Pt/Al2O3 (1.0 wt%, red): freshly prepared (solid curve), and hydrothermally aged under 10% CO2 + 10% H2O + N2 at 800 °C for 16 h (dash curve). The values of T50 (i.e., the temperature at which 50% conversion is achieved) are indicated in the plots. Inset: propane conversion of PtNiCo–PtNiOCoO/Al2O3 (black, 5.0 wt%) in comparison with commercial Pt/Al2O3 (red, 5.0 wt%) and Pt/Al2O3 prepared by the same method (blue, 5.0 wt%). Reactor: quartz tube microreactor packed with catalyst fixed bed at a flow rate of 50 ml min−1. The standard deviation is ±0.3%.
