丙烯是一种重要的化工原料,被广泛用于生产聚丙烯、丙烯腈、环氧丙烷等化工产品,也是塑料、橡胶、纤维三大合成材料的基本原料。由于对丙烯的需求量不断增长以及页岩气的广泛开采,丙烷脱氢(PDH)作为一种直接生产丙烯的工业技术备受关注。然而,商业上使用的铂(Pt)基催化剂活性组分容易烧结和团聚,导致积碳问题,很容易失去催化活性。因此,开发具有高活性和高稳定性的PDH催化剂具有重要意义。近年来,负载型Pt基催化剂在PDH反应中得到了广泛研究。从金属助剂优化和载体效应两个角度,综述了当前Pt基PDH催化剂的研究进展,特别是助剂和载体如何使Pt中心形成高度分散和稳定的活性位点,并系统总结了提高Pt基催化剂稳定性的策略。此外,还展望了Pt基催化剂在PDH反应中的发展方向。

Propylene is an important chemical raw material that is widely used in the production of pol⁃ypropylene, acrylonitrile, propylene oxide, and other chemical products. It is also the basic raw materi⁃al for the three major synthetic materials: Plastics, rubber, and fiber. Propane dehydrogenation(PDH) is an industrial technology attracting attention due to the growing demand for propylene and thelarge-scale extraction of shale gas. However, the active components of commercial platinum ( Pt -based) catalysts currently face challenges such as sintering, agglomeration, carbon build-up, rapidlydeactivation, and poor stability. Therefore, it is important to develop propane dehydrogenation catalystswith both high activity and high stability. In recent years, extensive research has been conducted onPt-based catalysts for propane dehydrogenation. This review provides a brief overview of the researchprogress on Pt-based catalysts, focusing on tuning additive metals and carrier effects. Specifically, itexplores how additives and carriers facilitate the formation of highly dispersed and stable active sites.Furthermore, the review presents future perspectives on the development of Pt-based catalysts for thepropane dehydrogenation reaction.
