Effective shell layer thickness of platinum for oxygen reduction reaction alloy catalysts.
Effects of surface Pt monolayer thickness on electrochemical oxygen reduction reaction of molecular-beam-epitaxially-prepared Pt/Ni/Pt(111) were investigated. The effective thickness of Pt for stabilizing the topmost surface can be deduced to be three monolayers.
