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.
通过在环境条件下直接在 4H Au NRBs 上生长 Ir，实现了 4H/面心立方（fcc）-Au@Ir 核壳纳米带（NRBs）的高产合成。重要的是，该方法可用于合成 4H/fcc-Au@Os 和 4H/fcc-Au@IrOs 核壳 NRBs。重要的是，所获得的 4H/fcc-Au@Ir 核壳 NRBs 在酸性条件下对析氧反应表现出异常高的电催化活性，远高于商业 Ir/C 催化剂。
