Engineering Fe–Ni Dual‑Atom Sites Via Ru Nanoclusters on 3D Carbon Aerogel for Enhanced Bifunctional Oxygen Electrocatalysis (IMAGE)
Caption
- A heterogeneous catalyst consisting of atomically dispersed FeN4 and NiN4 sites along with Ru6 nanoclusters anchored on a 3D carbon aerogel was synthesized.
- The Ru6 nanoclusters optimize the electron transfer from the Fe/Ni centers to the key intermediate (*OH) at the rate-determining steps.
- Zin–air battery employed FeN4–Ru6–NiN4@PCA as the air cathode catalysts achieves an exceptional long-term cycling stability for over 2000 h.
