Elucidating the surface compositions of Pd@PtnL core–shell nanocrystals through catalytic reactions and spectroscopy probes

Abstract

1 min read

Reaction and spectroscopy probes are exploited to analyze the surface dynamics of Pd@Pt nL nanocrystals. When calcined in the presence of oxygen, the underneath Pd atoms migrate out to the surface, causing changes to the surface composition.
