Abstract: The research progress on the catalysts，such as supported noble metal，metal oxide and metal modified zeolite，for nitrous oxide decomposition is reviewed. The advantages and disadvantages of the catalysts are discussed in detail. By comparison，the metal modified zeolite shows the better catalytic activity，which will be the focus in the future research.

摘要： 概述了用于催化分解温室气体N2O的贵金属、金属氧化物、分子筛等催化剂的研究进展，讨论了N2O催化分解的反应机理，分析了不同类型催化剂的特点及存在的问题。通过比较发现金属离子改性的分子筛催化剂活性较优，并展望了N2O催化分解研究的发展趋势。
