Reversible tuning of ultra-small multimetallic Pt-Pd-Rh-Ag nanoframes is achieved. These nanoframes showed tunable and reversible modes for the oxidation of small organic molecules by simply inducing segregation with adsorbates, such as SO and OH . This is the first example of reversible segregation under electrocatalytic conditions in atomic-sized electrocatalysts. These nanoframes also showed a controllable activity and good stability for the oxidation of small organic molecules.
实现了超小多金属 Pt-Pd-Rh-Ag 纳米框架的可还原调谐。通过简单地用吸附物（如 SO 和 OH ）诱导离析，这些纳米框架表现出对小分子氧化的可调谐和可逆模式。这是在原子尺度电催化剂中电催化条件下可还原离析的首例实例。这些纳米框架对小分子的氧化也表现出可控的活性和良好的稳定性。
