综述了近20年来贵金属催化剂上甲烷低温完全氧化的研究进展。对Pd/Al_2O_3催化剂体系进行了全面的讨论。综述了该催化剂上甲烷氧化的动力学方面，以及在Pd和PdO相上甲烷的活化行为(PdO在表面的形式、瞬时行为、活性中心的性质、金属颗粒大小的影响及其结构敏感性等)。简要讨论了除Al_2O_3载体外的其他氧化物担载的Pd催化剂。提出了非贵金属催化剂替代Pd催化剂的可能途径。
This paper reviews recent developments in complete oxidation of methane at low temperatures over noble metal catalysts in the past 20 years. The Pd/Al2O3 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 inuence of metal particle size and their structure sensitivities, and so on). Some Pd catalysts supported on other oxides besides the Al2O3 support are briey discussed. Possible routes of non-noble metal catalysts as substitutes for the Pd catalyst are also proposed.
