| 摘 要： | This paper reviews recent developments in complete oxidation of methane at low temperatures over noble metal catalysts in the past 20 years. The Pd/A1203 catalyst system is fully discussed. The review mainly focuses on the kinetic aspects of methane oxidation over this catalyst, and methane activation behavior over Pd and PdO phases (the form of PdO on the surface, transient behavior, the nature of the active sites, the influence of metal particle size and their structure sensitivities, and so on). Some Pd catalysts supported on other oxides besides the Al2O3 support are briefly discussed. Possible routes of non-noble metal catalysts as substitutes for the Pd catalyst are also proposed.
