Epitaxial Growth of Au–Pt–Ni Nanorods for Direct High Selectivity H₂O₂Production

Au–Ni core‐shell nanorods (NRs) and Au–Pt–Ni core‐sandwich‐shell NRs are synthesized and exhibit high activity for selective H₂O₂ 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.
