Abstract

Ultralong (∼25–30 μm) surface-Pt-rich Au₉₃Pt₇ alloy nanowires (ANWs) were achieved by a directional coalescence between spherical nanoparticles. Also, the ANWs exhibit superior electrocatalytic activity and long-term durability towards ethanol oxidation, ∼12 times in the mass activity better than the state-of-the-art commercial Pt/C catalyst.
