Au–Ni core‐shell nanorods (NRs) and Au–Pt–Ni core‐sandwich‐shell NRs are synthesized and exhibit high activity for selective H 2 O 2 production via direct oxygen reduction. The epitaxial growth with coherent lattice fringes allow for the tuning of the oxygen reduction pathway. Moreover, a selectivity of 95% and mass activity of 192.9 A g −1 noble metal are achieved using Au–Pt–Ni NRs at 150 mV overpotential.
