High-entropy intermetallics on ceria as efficient catalysts for the oxidative dehydrogenation of propane using CO(2)

The oxidative dehydrogenation of propane using CO(2) (CO(2)-ODP) is a promising technique for high-yield propylene production and CO(2) utilization. The development of a highly efficient catalyst for CO(2)-ODP is of great interest and benefit to the chemical industry as well as net zero emissions. H...

description The oxidative dehydrogenation of propane using CO(2) (CO(2)-ODP) is a promising technique for high-yield propylene production and CO(2) utilization. The development of a highly efficient catalyst for CO(2)-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 CeO(2) with a PtSn intermetallic structure exhibits a considerably higher catalytic activity, C(3)H(6) selectivity, long-term stability, and CO(2) utilization efficiency at 600 °C than previously reported. Multi-metallization of the Pt and Sn sites by Co/Ni and In/Ga, respectively, greatly enhances propylene selectivity, CO(2) activation ability, thermal stability, and regenerable ability. The results obtained in this study can promote carbon-neutralization of industrial processes for light alkane conversion.
