Propane Dehydrogenation on PtxSny (x, y ≤ 4) Clusters on Al2O3(110)

{With increasing interest in atomically dispersed and sub-nanometer Pt and Pt–Sn cluster catalysts for propane dehydrogenation (PDH), understanding structure–property relationships is of great importance. In this work, we present density functional theory calculations and microkinetic modeling of PDH on eight alumina-supported Ptx (x = 1–4) and PtxSny (x = 1–3
