Hydrothermal stability of Pd/ZrO2 catalysts for high temperature methane combustion

- Effect of calcination temperature of the support in the methane combustion.
- Good hydrothermal stability of Pd/ZrO2 catalysts was shown for methane combustion in the presence of water vapor.
- The ZrO2 support calcined at 900 °C exhibits the highest catalytic activity and stability.
- Catalytic activity depends on chemical species of Pd, and interaction between the Pd and support.
