Abstract: As a mild oxidant，CO₂ successfully prevents the deep oxidation of light alkanes in catalytic conversion，whereas the development of highly active and stable catalyst is the key to its applications. This paper reviews the recent development of catalysts for light alkanes catalytic conversion with CO₂ as oxidant，including catalysts for OMC（oxidative coupling of methane），and catalysts for the ODH （oxidative dehydrogenation）of ethane，propane and butane. The paper also discusses the role and related mechanisms of CO₂ in the reactions.

摘要： CO₂作为温和的氧化剂有效抑制了低碳烷烃催化转化过程中深度氧化的发生，然而其广泛应用还依赖于高效、高稳定性催化剂的研究与开发。本文就近年来国内外有关利用CO₂作为氧化剂在低碳烷烃催化转化反应方面的研究成果进行了综述，主要涉及甲烷氧化偶联制乙烯和乙烷催化剂；乙烷氧化脱氢制乙烯催化剂、丙烷氧化脱氢制丙烯催化剂和丁烷氧化脱氢制丁烯催化剂，分析讨论了CO₂作为氧化剂的作用和作用机制，并提出了研究展望。
