Abstract Single metals and bimetallics impregnated on γ-Al2O3 were screened for methane combustion. A screening of 20 noble metals was first performed in a fuel-rich condition, revealing the top six active metals: Rh, Ru, Pd, Pt, Cu, and Cr, in order of decreasing activity. Then, the screening of the combinations of these six metals delivered several catalysts that offered a higher methane conversion when compared to the most active single catalysts. (4 wt% Rh + 1 wt% Cr)/γ-Al2O3 achieved the highest methane combustion and provided excellent stability. NH3-TPD analysis revealed strong acid sites playing a key role in the activation of methane.
