Abstract

A novel metal monolithic anodic γ-Al₂O₃ support was prepared by anodization using a clad aluminum plate. The catalytic combustion of methane on Pt/Al₂O₃/Alloy, Pd/Al₂O₃/Alloy and Pd-Pt/Al₂O₃/Alloy catalysts prepared by the impregnation method was studied. The catalysts were characterized by ICP, BET, and temperature-programmed oxidation (TPO). The results showed that at low temperatures (<500°C), both Pd/Al₂O₃/Alloy and Pd-Pt/Al₂O₃/Alloy showed high activity, but the activity of Pt/Al₂O₃/ Alloy catalyst was very poor. At high temperatures (>700°C), Pd-Pt/Al₂O₃/Alloy showed the best activity among these three catalysts, whereas the activity of Pd/Al₂O₃/Alloy decreased gradually. Therefore, it was concluded that the co-existence of Pd and Pt in the Al₂O₃/Alloy support in Pd-Pt/Al₂O₃/Alloy made its activity the best among that of all the catalysts studied over the entire temperature range (400-800°C) considered for methane combustion.
