Unique mixed PtPd shelled PtPdCu alloy nanoparticle nanotubes (ANNTs) are synthesized by galvanic displacement with partial sacrificial copper nanowire templates, following electrochemical leaching of non‐noble metal Cu in acidic electrolyte, as reported by Shu‐Hong Yu and co‐workers on page 1182 . These core/shell catalysts can significantly reduce the amount of expensive Pt required and strongly improve electrocatalytic activity and durability through modified electronic structure, atomic distribution, and one dimensional structure property.
