Magnetic‐Field‐Enabled Ultrafast Quench Synthesis of Single‐Atom Catalysts for Efficient Anion Exchange Membrane Water Electrolysis

Angewandte Chemie, EarlyView.
We report a universal magnetic‐field‐enabled quench strategy for the ultrafast synthesis of diverse single‐atom catalysts within seconds. This simple and low‐cost method yields highly active catalysts with excellent performance in anion exchange membrane water electrolysis. ABSTRACT Single‐atom catalysts (SACs) play a critical role in diverse catalytic

Microenvironment Engineering as a Design Principle for Suppressing Catalyst Metal Loss

Angewandte Chemie, EarlyView.
Under ionomer‐containing microenvironments, nonporous carbon supports enhance the retention of dissolved platinum ions, whereas porous carbon supports promote pore‐confined redeposition and mitigate net platinum loss. ABSTRACT Stability losses in platinum electrocatalysts arise from dissolution, redeposition, and restructuring processes that are ...

Coupled Fe3O4‐Cluster Precipitates and Single Fe‐Atom Catalysts Can Boost Oxygen Reduction via Concomitantly Accelerated Water Dissociation

Angewandte Chemie, EarlyView.
Fe3O4 clusters can be precipitated onto Fe–N–C SACs through a residual‐oxygen‐assisted precipitation approach. Compelling evidence, including operando spectroscopy and ab initio calculations, suggests that Fe3O4‐cluster precipitates not only induce asymmetric electronic structures of Fe‐N4 active center to optimize the OH* adsorption, but also ...

Ketal Protection of Glycerol for Selective Electrosynthesis of Glyceric Acid in Highly Alkaline Media

Angewandte Chemie, EarlyView.
Using a ketal‐protected glycerol derivative (solketal) as the oxidation substrate enables site‐selective electrooxidation that suppresses C–C cleavage on non‐noble catalysts. Highly alkaline conditions promote reactive solketal alkoxide formation, weaken the Cα─H bond to facilitate dehydrogenation, and buffer local acidification, enabling a record‐high

Ketazine‐Linked Covalent Organic Framework for Metal‐Free Electrocatalytic Nitrate‐to‐Ammonia Conversion

Angewandte Chemie, EarlyView.
A metal‐free fluorinated ketazine‐linked COF is introduced as an efficient electrocatalyst for nitrate reduction to ammonia under neutral conditions. Fluorine substitution enhances π–π stacking and crystallinity, enabling a Faradaic efficiency of 59.9% and an NH3 yield rate of 1639.9 µmol h−1 mgCOF−1 at −0.9 V versus RHE. This establishes an unexplored
