Abstract

With the introduction of potassium species, the catalytic oxidation performance over the Pt₁/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.
