Abstract: The recent advances in using of N2O as oxidative dehydrogenating agent were reviewed. The new investigation of N2O used in oxidative dehydrogenation of n-butane，propane and benzene was summarized. The discussion was focused on the oxidative dehydrogenation of ethylbenzene to styrene in the presence of N2O and the role of N2O in the oxidative dehydrogenation reactions. Finally，research trend of renovating catalysts，developing new catalyst materials and studying the mechanism of oxidative dehydrogenation of ethylbenzene to styrene in the presence of N2O was discussed.

摘要： 综述了N2O作为氧化脱氢剂用于氧化还原体系的研究进展，介绍了N2O正丁烷氧化脱氢体系、丙烷氧化脱氢体系、N2O氧化苯制苯酚体系的研究结果，并重点总结了N2O氧化脱氢制苯乙烯的研究进展，讨论了N2O作为氧化脱氢剂的作用机制，认为今后应在催化剂改进、催化新材料的开发和N2O氧化脱氢反应机理等方面开展深入的研究，有效拓展N2O氧化脱氢剂的应用领域。
