Enhanced oxygen reduction activity of platinum subnanocluster catalysts through charge redistribution

Chem Commun (Camb). 2019 Oct 17;55(84):12603-12606. doi: 10.1039/c9cc06327g.

Abstract

Single-size platinum Pt6 subnanoclusters exhibit superior mass-specific and surface-specific activities for the oxygen reduction reaction. The enhanced activity is attributed to polarized electron distributions based on rigorous structure characterization by X-ray absorption fine structure spectroscopy and density functional theory.
