摘　　要：本文详细综述了用于Ｎ２Ｏ直接分解催化剂的研究进展情况。Ｎ２Ｏ分解催化剂大致可以分作以下几类，即：（１）稀土氧化物及相关氧化物；（２）复合金属氧化物；（３）沸石催化剂；（４）水滑石热分解产物催化剂。前两类催化剂注重探讨催化分解Ｎ２Ｏ的机理；而后两类催化剂主要研究催化分解Ｎ２Ｏ的活性。The research progress on the catalysts for nitrous oxide decomposition was reviewed in detail. The catalysts for nitrous oxide decomposition could be divided into four types:(1) rare earth sesquioxides and related oxides;(2) mixed metal oxides;(3) metal exchanged zeolites;(4) thermally calcined hydrotalcites. The former two kinds of catalysts were focused on a mechanistic understanding of N 2O decomposition;While the latter two kinds of catalysts were focused on the catalytic activities for N 2O decomposition.
