• Recent advance in direct dehydrogenation of propane to propylene are reviewed. • The metal-support interaction in catalytic performance is elucidated. • The catalyst stability and deactivation mechanisms are analyzed. • Developments of zeolite confined metal cluster catalysts is prospected. Propane dehydrogenation to propylene provides a promising route to address the problem of insufficient supply of propylene and the utilization of shale gas resources. Although significant progress has been made in direct propane dehydrogenation (PDH), the exploitation of efficient catalysts remains a great challenge. Zeolite confined metal cluster catalysts have been utilized for propane dehydrogenation to propylene due to their excellent catalytic performance and stability, but there are relatively few systematic and comprehensive reviews on zeolite confined metal cluster catalysts. Herein, recent advances of zeolite confined metal cluster catalysts for direct propane dehydrogenation to propylene are highlighted. The electronic coordination of catalysts, the influence of structure on catalytic performance, catalyst stability, and the reaction mechanism have been systematically analyzed and summarized. Meanwhile, the influence of promoter on the catalytic performance of catalysts, the interaction between metal and support to enhance catalyst stability as well as the mechanism of catalyst deactivation are illustrated in depth. In addition, we present the development challenges and future opportunities of direct propane dehydrogenation to propylene. The aim of this review is to explore the direct propane dehydrogenation to propylene reaction from a comprehensive perspective to promote the development of novel and efficient catalysts and accelerate the industrialization of this process.
