Embedded Fe‐Cu Pairs Enable Tandem Nitrate‐to‐Ammonia Electroreduction

Advanced Materials, EarlyView.
A tandem Fe‐Cu pair catalyst, composing a single copper atom (Cu–N3) coordinated to adjacent iron clusters (Fe3N8), is designed. The electron‐deficient copper sites markedly enhance nitrate adsorption, while the electron‐rich iron clusters facilitate nitrite adsorption and water activation, thereby accelerating the electroreduction of nitrate and ...

Tuning Active Hydrogen on Reconstructed RuO2/Co(OH)2 Catalysts for Selective Ammonia Synthesis

Advanced Materials, EarlyView.
A combined approach of precatalyst design and electrolyte engineering is employed to develop highly active, selective, and stable catalysts for electrochemical nitrate reduction. In alkaline media, the reconstructed RuO2/Co(OH)2 catalyst demonstrates impressive performance in ammonia synthesis, rechargeable Zn‐NO3− battery, and the remediation of ...

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...
