Volcano-Shaped Relationship Between Pt-Skin Thickness and ORR Activity.

Caption

This figure illustrates the volcano-type trend between Pt-skin layer thickness and oxygen-reduction reaction performance. Mass activity peaks at two Pt layers, where the optimal interplay of strain and ligand effects lowers the d-band center and maximizes catalytic efficiency. Structural models show how varying Pt-skin thickness reshapes electronic properties across the PtCu@PtnL series.
