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.

浸渍在γ-Al系金属单质和bimetallics ₂ ö ₃筛选甲烷燃烧。首先在富含燃料的条件下进行20种贵金属的筛选，以活性降低的顺序显示了前六种活性金属：Rh，Ru，Pd，Pt，Cu和Cr。然后，对这六种金属的组合进行了筛选，得到了几种催化剂，与活性最高的单一催化剂相比，甲烷的甲烷转化率更高。（4重量％的Rh + 1重量％的Cr）/γ-Al系₂ ö ₃实现的最高甲烷燃烧和提供极好的稳定性。NH ₃ -TPD分析表明强酸位在甲烷活化中起关键作用。
