Separating Hydrogen Evolution From Electroplating in Zn Metal Batteries Using Scanning Electrochemical Microscopy

Advanced Energy Materials, EarlyView.
Operando SECM decouples hydrogen evolution from other degradation pathways in Zn metal batteries by quantifying its contribution during Zn electrodeposition. Although HER is shown to account for only a minor fraction of the irreversible charge loss, it remains a key indicator of interfacial evolution and by‐product formation governing cycling ...

Pt Single‐Atom Catalysts on FTO for Optically Invisible pH‐Universal Hydrogen Evolution Electrodes

Advanced Energy Materials, EarlyView.
Comparison of the overpotential (η) at 10 mA cm−2 in acidic electrolyte of Pt SA on FTO (this work) and other literature. ABSTRACT Transparent hydrogen‐evolution electrodes are essential for photoelectrochemical and optoelectronic energy‐conversion devices, yet typically suffer from a trade‐off between catalytic activity and optical transmission. Here,

Water‐Mediated Proton Facilitation for Stable Acidic CO2 Electrocatalysis

Advanced Energy Materials, EarlyView.
Proton‐mitigating Cu─O─Ce sites accelerate *CO formation and PCET‐mediated *CO─*CHO coupling, enabling efficient multicarbon production at relatively low current density. Maintaining a retentive acidic pH suppresses parasitic hydrogen evolution and preserves in situ CO2 availability for carbon‐efficient acidic CO2 reduction.

Interfacial Electronic Modulation of Vacancy‐Stabilized Pt Sites in Mo‐NiSeO4/NiSe2 Heterostructures for Industrial Alkaline Water Electrolysis

Advanced Energy Materials, EarlyView.
A vacancy‐stabilized Pt,Mo‐NiSeO4/NiSe2@Co2P heterostructure with atomically dispersed Pt sites and Mo‐regulated electronic structure enables efficient bifunctional water splitting. Strong interfacial coupling and defect‐assisted Pt stabilization promote rapid charge transfer and optimized intermediate adsorption, delivering outstanding HER/OER ...

Programming Structural Disorder in MOFs for a Stable Bifunctional Water‐Splitting Electrocatalyst

Advanced Energy Materials, EarlyView.
Introducing structural disorder into a highly active metal–organic framework enhances its stability. This improvement arises from the mitigation of destructive reconstruction during activation, thereby maintaining structural integrity and enabling long‐term durability.

Configurational Entropy and Compositional Effects in Fe‐Based Oxide 2D Sheets for Nitrate Electroreduction

Advanced Energy Materials, EarlyView.
FeCuCoMnZnOx integrates diverse heteroatomic bridge‐site environments and composition‐dependent electronic structures to promote nitrate activation and sequential hydrogenation toward ammonia, demonstrating that nitrate reduction reaction performance is governed by the combined effects of composition and local coordination rather than configurational ...

Exploring Quantum Support Vector Regression for Predicting Hydrogen Storage Capacity of Nanoporous Materials

Advanced Intelligent Discovery, EarlyView.
In this study we employed support vector regressor and quantum support vector regressor to predict the hydrogen storage capacity of metal–organic frameworks using structural and physicochemical descriptors. This study presents a comparative analysis of classical support vector regression (SVR) and quantum support vector regression (QSVR) in predicting ...

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.

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 ...

From Word2Vec to Transformers: Text‐Derived Composition Embeddings for Filtering Combinatorial Electrocatalysts

Advanced Intelligent Discovery, EarlyView.
With the downstream filter held fixed, text‐derived composition representations produce distinct screening outcomes across 14 electrocatalyst libraries. Embedding model and composition encoding control the trade‐off between candidate reduction and preservation of the best measured current.
