Platinum (Pt)-based nanostructures are the most efficient catalysts for the oxygen reduction reaction (ORR) in acid media. Here, Pt Ni wavelike nanowires (W-NWs) have been synthesized by etching Pt Ni@PtNi core-shell nanowires with 2,5-dihydroxyterephthalic acid for 24 hours. Compared to the commercial Pt/C catalyst, the free-standing Pt Ni W-NWs show improvements of up to 9.3 times for mass activity and 12.6 times for specific activity, respectively.
