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

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.
