Biomimetic Synthesis of an Ultrathin Platinum Nanowire Network with a High Twin Density for Enhanced Electrocatalytic Activity and Durability

Structure-enhanced catalytic activity: An ultrathin platinum multiple-twinned nanowire network is shown to be an efficient electrocatalyst (see picture). This material has a higher electrochemical surface area and exhibits a much improved activity toward both the oxygen reduction reaction and the methanol oxidation reaction relative to commercial Pt/C catalysts.
