Trimetallic Au/Ag/Pt hetero‐nanostructures (AAPHNs) with distinctive, designed morphology are synthesized by galvanic replacement reaction and a site‐selective strategy. The three metals present on the surface are shown to act synergistically to enhance the electro‐catalytic performance and durability for methanol oxidation. The described structural modification of the nanocomposites increases the range of potential applications to include both the oxygen reduction reaction in fuel cells and photocatalysis of the hydrogen evolution reaction.
