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.

Chiral‐Encoded Pt‐Ir Surfaces as Apparent Spin Filter for Enhanced Oxygen Reduction

Advanced Science, EarlyView.
The Chiral‐Induced Spin Selectivity (CISS) effect is employed in chiral‐encoded mesoporous Platinum‐Iridium (Pt‐Ir) electrocatalysts to enhance the oxygen reduction reaction (ORR). A break in spin symmetry leads to a substantial antagonistic difference in activity (>200%) when comparing two enantiomorphs of the same electrode.
