Abstract

Peak performance: Electrochemical experiments show that the oxygen reduction reaction (ORR) on platinum monolayers supported on various transition metals exhibits a volcano-type behavior (see graph). Calculations reveal that bond-breaking occurs more easily as bond-making becomes harder, and why the Pd-supported Pt monolayer (PtML/Pd(111)) has higher ORR activity than pure Pt(111).
