The catalytic oxidation performance of the Pt-1/CeO2 catalyst was greatly improved with the introduction of potassium species. Potassium ions acted as structural and electronic promoters, forming Pt-O-K interactions with Pt to directly regulate the coordination environment and electronic state of Pt, as well as the metal-support interaction between Pt and CeO2.
With the introduction of potassium species, the catalytic oxidation performance over the Pt-1/CeO2 catalyst was significantly enhanced, where potassium ions acted as structural and electronic promoters, and formed Pt-O-K interactions with Pt to directly regulate the coordination environment and electronic state of Pt and the metal-support interaction between Pt and CeO2.
