Abstract
The controlled synthesis of mixed‐PtPd‐shell PtPdCu‐alloy nanoparticle nanotubes (ANNTs) is demonstrated by galvanic displacement with partially sacrificial copper‐nanowire templates, and following the electrochemical leaching of the non‐noble metal Cu in the acidic electrolyte. These core‐shell catalysts significantly reduce the amount of expensive Pt and highly improve the electrocatalytic activity and durability through their modified electronic structure, atomic distribution, and 1D structure property.
