Ag─S Sites Steer Furfural Electroreduction to Furfuryl Alcohol

Angewandte Chemie, EarlyView.
A simple sulfide incorporation strategy turns silver into a highly active and selective catalyst for furfural electroreduction to furfuryl alcohol. Experiments combined with density functional theory reveal how isolated S sites promote hydrogenation while suppressing hydrofuroin coupling, enabling selective biomass upgrading.

Unlocking Three‐Dimensional Electron and Ion Transport in High‐Loading and Dense Lithium‐Ion Battery Electrodes Assisted via Porous Graphene Networks

Advanced Energy Materials, EarlyView.
Graphene mesosponge (GMS) enables three‐dimensional electron and ion transport in high‐loading, densely packed lithium‐ion‐battery electrodes through its unique mesoporous structure. The three‐dimensionally interconnected carbon network and electrolyte retained within the GMS mesopores ensure efficient electronic and ionic conduction, respectively ...

Mechanochemically Disordered Li2Ta2OCl10 Oxyhalide Unlocks Superionic Conductivity (>10 mS.cm−1)

Advanced Energy Materials, EarlyView.
This work presents a new crystalline oxyhalide, Li2Ta2OCl10, built from [Ta2OCl10]2− dimers. The disorder induced by ball‐milling drives the dramatic 5000‐fold increase in ionic conductivity to reach 11 mS.cm−1. The material shows promise as a solid electrolyte for batteries and opens new prospects for the discovery of new dimer‐based compounds ...

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

Angewandte 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.

Chloride‐Mediated Activation of Aluminum‐Alloyed Liquid Metal Anodes for Stretchable Asymmetric Energy Storage

Advanced Energy Materials, EarlyView.
A gallium‐centered cell pairs an aluminum‐alloyed GaIn anode with a GaOOH cathode in a chloride‐rich water‐in‐ionic‐liquid electrolyte. Chlorogallate ions dissolve the native oxide that normally seals the liquid metal, and preferentially reduce indium seeds to oxide‐free clusters on which gallium plates and strips reversibly.

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

Advanced 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.

Site‐Selective Anion‐Cation Regulation of Sulfide Electrolyte Enables Low‐Pressure Dendrite‐Suppressed All‐Solid‐State Lithium Metal Batteries

Angewandte Chemie, EarlyView.
Site‐selective Al/F/Cl regulation couples sulfide‐framework stabilization with favorable interphase chemistry in argyrodite Li6PS5Cl. Al incorporation reinforces the redox‐sensitive tetrahedral framework, while F/Cl regulation promotes Li+ transport and guides the formation of a LiF/LiCl‐rich passivation interphase.
