High methane combustion activity of PdO/CeO2–ZrO2–NiO/γ-Al2O3 catalysts

PdO/CeO2–ZrO2–NiO/γ-Al2O3 catalysts were prepared for the combustion of methane at moderate temperatures. The introduction of a small amount of NiO within the cubic fluorite CeO2–ZrO2 structure as a promoter effectively enhanced the oxygen release and storage abilities of the catalysts, thereby achi...
