Synergistic effect of scattered rare metals on Pt/CeO₂ for propane oxidative dehydrogenation with CO₂.

ABSTRACT: The oxidative dehydrogenation of propane with CO₂ (CO₂-ODP) is a green industrial process for producing propene. Cerium oxide-supported platinum-based (Pt/CeO₂) catalysts exhibit remarkable reactivity toward propane and CO₂ due to the unique delicate balance of C-H and C[double bond, length as m-dash]O bond activation. However, the simultaneous activation and cleavage of C-H, C-C, and C-O bonds on Pt/CeO₂-based catalysts may substantially impede the selective activation of C-H bonds during the CO₂-ODP process. Here, we report that the scattered rare metal oxide (SRO _x , SR = Ga, In) overlayer on Pt/CeO₂ exhibits extraordinary activity and selectivity for the CO₂-ODP reaction. With the
