Enhanced stability and activity of Pt–Y alloy catalysts for electrocatalytic oxygen reduction

Author affiliations

Abstract

We report Pt-based alloys with early transition metals. Significant electrocatalysis occurs during oxygen reduction reaction (ORR) at the Pt–Y alloy electrodes, and the extent depends on the alloy composition. The Pt–Y alloy electrode activity is related to the d-band center position, and the lattice strain and stability for oxygen reduction reaction.
