Characterizing Biopolymer Electrolytes in Zinc–Air Batteries: Challenges, Best Practices, and a Robust Workflow Guiding Future Research Paths

open access: yesAdvanced Energy Materials, EarlyView.
Bio‐based gel polymer electrolytes promise sustainable, mechanically adaptable zinc–air batteries, yet their progress is constrained by inconsistent characterization. This review critically links formulation, structure, interfaces, and cell performance, identifies methodological gaps under alkaline operating conditions, and proposes application ...

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

open access: yesAdvanced 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 ...

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

open access: yesAdvanced 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 ...

Ionomer‐Free Iridium Anodes With Low Loading for Zero‐Gap Electrolyzers via Direct Atomic Layer Deposition

open access: yesAdvanced Energy Materials, EarlyView.
Iridium‐based anode catalyst layers for proton exchange membrane water electrolysis were fabricated via atomic layer deposition (ALD). Using custom‐made microporous substrates and thermal ALD, current densities of up to 2.5 A·cm−2${\rm A}\cdot{\rm cm}^{-2}$ at 0.21 mg·cm−2$\text{mg}\cdot {\text{cm}}^{-2}$ Ir loading were achieved.

Enhanced Hydrogen Evolution Activity of MoS2 Through Solid Solution Modification of Its Edge Sites With Ruthenium

open access: yesAngewandte Chemie, EarlyView.
Modulating the edge sites of molybdenum disulfide significantly boosts hydrogen production. By depositing Ru to form an edge‐coordinated solid solution, we accelerate water dissociation and shift the hydrogen evolution reaction pathway to Volmer–Tafel.

Synergistic Fluoride and Polymer‑Regulated Interfacial Engineering of NiFe‑LDH Anodes for Ampere‑Scale Natural Seawater Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
Schematic comparison of optimized F–NiFe–LDH and conventional NiFe–LDH electrodes during alkaline natural seawater oxygen evolution. The synergistic (poly)CM protective layer and fluoride‐mediated passivation suppress metal leaching, mitigate chloride‐induced corrosion, and regulate surface reconstruction, preserving catalyst integrity beyond 1000 h ...

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

open access: yesAdvanced 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.

Bromide–Borate Coupling Enables Selective Electrochemical Oxidation of Glycerol to Dihydroxyacetone

open access: yesAngewandte Chemie, EarlyView.
Bromide–borate coupling enables selective electrochemical upgrading of glycerol to dihydroxyacetone (DHA). Electrogenerated bromine species mediate glycerol oxidation, while borate coordination biases selectivity toward DHA, enabling carbon‐balanced oxidation and high productivity in flow‐cell operation.

From Atoms to Reactors: A Critical Review of a Decade of Machine Learning in Heterogeneous Catalysis (2017–2026)

open access: yesAngewandte Chemie, EarlyView.
Machine learning has digitalized heterogeneous catalysis from the top of the length scale downward: prediction at the atom and the material is now mature, yet the reactor and the process remain the open frontier. This critical review traces a decade of progress across the full catalytic value chain and asks where the next decade of impact must be won ...
