PtCu and PtPdCu Concave Nanocubes with High‐Index Facets and Superior Electrocatalytic Activity

Abstract

PtCu nanostructures: PtCu nanocubes (NCs), concave nanocubes (CNCs), and PtPdCu CNCs with high-index facets (HIFs) were prepared through progressive galvanic replacements in a one-pot hydrothermal approach. The HIF-enclosed CNCs showed superior activities to (100)-enclosed NC catalysts for methanol oxidations owing to the modification of both the surface electronic structures and the surface atomic arrangements (see figure).
