One-pot synthesis and electrocatalytic activity of octapodal Au–Pd nanoparticles

Abstract

Bimetallic alloy Au–Pd nanoparticles with an unprecedented octapodal shape have been prepared by a one-pot aqueous synthesis method. This unique structure was produced through selective etching of {100} facets by in situ generated Br⁻ ions. The octapodal Au–Pd nanoparticles exhibited efficient electrocatalytic properties toward ethanol oxidation.
