Oxidative dehydrogenation of propane in the presence of carbon dioxide (ODPC) is a sustainable approach and an attractive catalytic route for propylene production with less environmental footprint than the conventional oxidative dehydrogenation path with oxygen. Researchers have considered CO₂ as a mild oxidant that can overcome the problems of over-oxidation and low propylene selectivity, that are typically associated with the current synthesis routes. This article provides a critical review on the current mechanistic understanding of three different catalyst types used in the ODPC reaction based on experimental studies; (i) zeolites with different frameworks, (ii) porous materials-supported metal oxides, and (iii) transition metal oxides and other metal catalysts. A detailed review of the literature compares the framework, pore structure, nature of active sites, reducibility, and the role of promoters and supports for each type of catalytic materials in the absence and presence of CO₂, and is followed by a thorough discussion on the promotional effects of CO₂ as a soft oxidant on CH bond scission. Future directions with respect to materials design, synthesis and reaction conditions are also discussed.

丙烷在二氧化碳（ODPC）存在下的氧化脱氢是一种可持续的方法，并且是一种有吸引力的催化生产丙烯的方法，与传统的氧气氧化脱氢方法相比，其环境足迹小。研究人员已经考虑了CO ₂作为一种温和的氧化剂，可以克服通常与当前合成路线相关的过氧化和丙烯选择性低的问题。本文根据实验研究对目前对ODPC反应中使用的三种不同催化剂类型的机理进行了深入的综述。（i）具有不同骨架的沸石，（ii）多孔材料负载的金属氧化物，和（iii）过渡金属氧化物和其他金属催化剂。文献的详细综述比较了在不存在和存在CO ₂的情况下每种类型催化材料的骨架，孔结构，活性位点的性质，还原性以及促进剂和载体的作用，随后对CO ₂的促进作用作为C H键断裂时的软氧化剂。还讨论了有关材料设计，合成和反应条件的未来方向。
