The high‐yield synthesis of 4H/face‐centered cubic ( fcc )‐Au@Ir core‐shell nanoribbons (NRBs) is achieved via the direct growth of Ir on 4H Au NRBs under ambient conditions. Importantly, this method can be used to synthesize 4H/ fcc ‐Au@Os and 4H/ fcc ‐Au@IrOs core‐shell NRBs. Significantly, the obtained 4H/ fcc ‐Au@Ir core‐shell NRBs demonstrate an exceptional electrocatalytic activity toward the oxygen evolution reaction under acidic condition, which is much higher than that of the commercial Ir/C catalyst.
