Insights into dynamic surface processes occurring in Rh supported on Zr-grafted γ-Al2O3 during dry reforming of methane

- Rh supported on Zr-grafted γ-Al2O3 is highly active for CO2 methane reforming (DRM).
- Grafting method leads to mixture of Rh/γ-Al2O3 and Rh/ZrO2 catalysts in good contact.
- Catalytic synergy between Rh/γ-Al2O3 and Rh/ZrO2 may occur due to oxygen mobility.
- Presence of oxidized and metallic Rh seems to be key factor for high activity in DRM.
