Propane direct dehydrogenation (PDH) is an attractive technology for propylene production that has received extensive attention. Molecular sieves with uniform porous structure, high thermal stability, and unique confinement capability have been proven to be ideal supports for well-dispersed active sites to generate efficient PDH performance. In this review, we describe the progress in the synthesis and PDH performance of metal-molecular sieve catalysts, including metal-mesoporous silica, metal-zeolite, and metal-hierarchical zeolite catalysts. The strategies in identifying and regulating active site microstructure and metal-molecular sieve interactions as well as their correlations with active site structure and PDH mechanism are introduced simultaneously. Finally, the current limitations and future opportunities of metal-molecular sieve materials in the PDH reaction are also discussed. This review is expected to provide some guidance for future catalyst design based on utilizing the molecular sieve’s structural confinement to facilitate propane activation and active site stabilization.

丙烷脱氢金属分子筛催化剂的最新进展
丙烷直接脱氢（PDH）是一种极具吸引力的丙烯生产技术，受到了广泛关注。具有均匀多孔结构、高热稳定性和独特限制能力的分子筛已被证明是良好分散的活性位点产生高效 PDH 性能的理想载体。在这篇综述中，我们描述了金属-分子筛催化剂的合成和 PDH 性能的进展，包括金属-介孔二氧化硅、金属-沸石和金属-多级沸石催化剂。同时介绍了识别和调节活性位点微观结构和金属-分子筛相互作用的策略及其与活性位点结构和PDH机理的相关性。最后，还讨论了金属分子筛材料在 PDH 反应中的当前局限性和未来机遇。这篇综述有望为未来基于利用分子筛的结构限制来促进丙烷活化和活性位点稳定的催化剂设计提供一些指导。
