Single-atom Zr promoter boosts oxygen activation on ceria-supported Pt catalysts

Preparation of isolated Zr promoter on CeO₂

Zr₁-CeO₂ with 2 wt% Zr loading was synthesized by incorporating Zr cations into CeO₂ through the atom-trapping method (Fig. 1a)¹⁴. The atom-trapping method creates a unique…
