摘　　要：综述了甲烷催化燃烧催化剂的研究现状,介绍了近年来有关Pd,Pt,Rh,Au等贵金属和金属氧化物催化剂的制备方法及催化性能方面的研究结果,指出了催化活性和高温催化稳定性是评价甲烷燃烧催化剂性能的两个关键因素.通过掺杂一些金属和金属氧化物,不但可以提高高活性贵金属催化剂的热分解温度,还可以提高高温催化剂(如钙钛矿和六铝酸盐材料等)的催化活性.The recent research progress and developments of the catalysts for methane catalytic combustion were described in this paper. The preparation methods and catalytic activities of catalysts based on Pd, Pt, Rh, Au noble metals and metal-oxides were briefly summarized and assessed. It is also pointed out that catalytic activity and heat resistant are the two key factors for methane catalytic combustion. It is shown that the addition of metals and metal|oxides improves the thermal stability of noble metal catalysts and metal-oxide catalysts such as perovskites and hexaaluminates, and brings benefit to activity in methane catalytic combustion.
