Wrinkled Strain‐Enriched High‐Entropy Metallene Enables Cross‐Site Tandem Nitrate‐to‐Ammonia

Angewandte Chemie, EarlyView.
A wrinkled 2D PdFeCoNiCuIn high‐entropy metallene overcomes the low atom utilization of high‐entropy alloys. Indium‐induced strain and p‐d hybridization enable a cross‐site tandem pathway for nitrate reduction to ammonia. It achieves 99.3% Faradaic efficiency and an NH3 yield rate of 4.55 mmol h−1 mgcat−1.
