Pt/Ce_0.5Zr_0.5O₂ (denoted as Pt/CZ11) and Pt/Al₂O₃ with identical Pt loading and dispersion were prepared and evaluated for ethane catalytic combustion. Pt/CZ11 exhibited higher activity than Pt/γ-Al₂O₃ even with similar Pt dispersion. Combined with various characterizations, it was revealed that the enrichments of surface active oxygen and oxygen vacancy on Pt/CZ11 facilitated ethane combustion owing to the strong interaction between Pt and Ce-Zr solid solution. Moreover, in situ DRIFT results demonstrated that different reaction mechanisms were followed over Pt/CZ11 and Pt/Al₂O₃. The front followed the single-site Langmuir-Hinshelwood (L-H), in which C₂H₆ and O₂ were absorbed and activated on Pt sites. While the coupled reaction mechanism involving L-H and Mars-van Krevelen (MvK) were illustrated over Pt/CZ11, on which ethane can be activated on Pt sites and CZ11 support. More mechanistic insights into ethane combustion provided the guidelines for the developments of catalysts with superior performance for light-carbon alkane volatile organic compounds.

Pt/Ce _0.5 Zr _0.5 O ₂ (表示为Pt/CZ11)和Pt/Al ₂ O ₃具有相同的Pt负载和分散被制备并评价乙烷催化燃烧。即使具有相似的 Pt 分散，Pt/CZ11 也表现出比 Pt/γ-Al ₂ O ₃更高的活性。结合各种表征，表明由于 Pt 和 Ce-Zr 固溶体之间的强相互作用，Pt/CZ11 表面活性氧和氧空位的富集促进了乙烷燃烧。此外，原位漂移结果表明 Pt/CZ11 和 Pt/Al ₂ O ₃遵循不同的反应机制. 前沿沿单点朗缪尔-欣谢尔伍德 (LH)，其中 C ₂ H ₆和 O ₂在 Pt 位点上被吸收和激活。虽然在 Pt/CZ11 上说明了涉及 LH 和 Mars-van Krevelen (MvK) 的耦合反应机制，在 Pt/CZ11 上可以在 Pt 位点和 CZ11 载体上激活乙烷。对乙烷燃烧的更多机理见解为开发对轻碳烷烃挥发性有机化合物具有卓越性能的催化剂提供了指导。
