Synthesis of Pt–Cu Nanodendrites through Controlled Reduction Kinetics for Enhanced Methanol Electro‐Oxidation

Final reductions: Alloyed Pt–Cu nanodendrites are synthesized through a two-step co-reduction method, in which the reduction rate is controlled by the oxidative etchants and the reducing agents. These dendritic nanostructures are the result of overgrowth along the <111> axis of the face-centered cubic structure and the coalescence of small dendritic seeds. These nanodendrites are highly active for methanol electro-oxidation because of their unique structure and the bifunctionality of Pt and Cu.
