High-entropy intermetallics on ceria as efficient catalysts for the oxidative dehydrogenation of propane using CO₂.

ABSTRACT: The oxidative dehydrogenation of propane using CO₂ (CO₂-ODP) is a promising technique for high-yield propylene production and CO₂ utilization. The development of a highly efficient catalyst for CO₂-ODP is of great interest and benefit to the chemical industry as well as net zero emissions. Here, we report a unique catalyst material and design concept based on high-entropy intermetallics for this challenging chemistry. A senary (PtCoNi)(SnInGa) catalyst supported on CeO₂ with a PtSn intermetallic structure exhibits a considerably higher catalytic activity, C₃H₆ selectivity, long-term stability, and CO₂ utilization efficiency at 600 °C than previously reported.
