Carbon‐Confined Fe3C/Fe3N Janus Interfaces for Selective Nitric Oxide‐to‐Ammonia Electroreduction

Angewandte Chemie, EarlyView.
A defect‐rich, graphitic‐carbon‐confined Fe3C/Fe3N Janus catalyst integrates NO transport, adsorption/activation, and interfacial H supply for efficient nitric oxide electroreduction to ammonia. Built from earth‐abundant elements, this architecture enables high‐yield and high‐efficiency NH3 synthesis while valorizing industrial NO emissions.

FastCat: Autonomous Discovery of Multielement Layered Double Hydroxide Alloy Catalysts for Alkaline Oxygen Evolution Reaction

Advanced Intelligent Discovery, EarlyView.
A machine learning‐guided self‐driving laboratory screened over 500 nickel‐based layered double‐hydroxide catalysts for alkaline oxygen evolution. Out of the eight metals, the robot uncovered a quaternary Ni–Fe–Cr–Co catalysts requiring only 231 mV overpotential to reach 20 mA cm−2.

Enriched and Sustained Oxygen Vacancies in Amorphous NiWOx Enhance and Stabilize Urea Electrooxidation

Angewandte Chemie, EarlyView.
We propose an “amorphous oxygen mechanism (AOM)” for urea electrooxidation on amorphous NiWOx with tunable Ov, which achieves robust UOR activity and stability simultaneously. The “amorphous oxygen” in NiWOx prefers to escape during the UOR, in situ generating and stabilizing Ov, which thermodynamically promotes the reaction.

Machine Learning‐Assisted Second‐Order Perturbation Theory for Chemical Potential Correction Toward Hubbard U Determination

Advanced Intelligent Discovery, EarlyView.
In this work, the Doubao large language model (LLM) is involved in the formula derivation processes for Hubbard U determination regarding the second‐order perturbations of the chemical potential. The core ML tool is optimized for physical domain knowledge, which is not limited to parameter prediction but rather serves as an interactive physical theory ...

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
