One-pot fabrication of single-crystalline octahedral Pt–Cu nanoframes and their enhanced electrocatalytic activity†
Abstract
Octahedral Pt–Cu nanoframes have been synthesized by a one-pot aqueous method. Due to the unique structure and possible synergetic effect of Pt and Cu components, these octahedral Pt–Cu nanoframes exhibited significantly enhanced catalytic activity toward the electro-oxidation of
