Effect of Addition of Pt, La2O3, Nd2O3 and ZrO2 to PdO/Al2O3 on Catalytic Combustion of Methane

The addition of Pt prolongs the lifetime of the PdO/Al2O3 catalyst during CH4 combustion at 1073 K. Furthermore, the addition of ZrO2, La2O3 and Nd2O3 greatly extends the lifetime of the Pt–PdO/Al2O3 catalyst. This is due not to the transformation of PdO to Pd–Pt but to the prevention of the growth...

Description
Summary:The addition of Pt prolongs the lifetime of the PdO/Al2O3 catalyst during CH4 combustion at 1073 K. Furthermore, the addition of ZrO2, La2O3 and Nd2O3 greatly extends the lifetime of the Pt–PdO/Al2O3 catalyst. This is due not to the transformation of PdO to Pd–Pt but to the prevention of the growth of PdO particles during the reaction.
