Mixed‐Valence Atomic‐Layer Iridium Patches Enhance Alkaline Hydrogen Evolution

Advanced Science, EarlyView.
Engineering iridium architectures on Cu3P nanowires reveals that atomic‐layer Ir patches form a mixed‐valence interfacial motif with an anisotropic electronic structure. This configuration balances water dissociation and hydrogen adsorption/desorption, delivering superior alkaline hydrogen evolution with a 27 mV overpotential and 1 A cm−2 operation in ...

Pt‐Regulated Dynamic Cu(0) Regeneration in CuPt Alloy Enables High‐Efficiency Self‐Driven Formaldehyde Fuel Cells for Potassium Formate Production

Advanced Science, EarlyView.
In this work, a Cu30PtX/CF anode material was synthesized to effectively catalyze the electrocatalytic formaldehyde oxidation, and thereby assembled a fuel cell that offered a high open‐circuit potential of 0.94 V and a power density of 34.3 mW cm−2. This work realizes the co‐generation of electrical energy and high‐value‐added chemicals with nearly ...

Bioelectrochemically Powered Out‐of‐Equilibrium Hydrogels Enable Feedback‐Regulated Functions

Advanced Science, EarlyView.
A bioelectrochemically powered hydrogel operates far from equilibrium via an antagonistic redox cycle that regulates disulfide exchange within a polyrotaxane network. Coupling electrochemical mediator cycling with enzymatic feedback enables dynamic control of hydrogel mechanics and transport properties, driving glucose‐responsive insulin release with ...

Sodiophilic Na3Sb Framework‐Regulated Sodium Deposition and Interphase Evolution for Dendrite‐Free and Long‐Life Sodium Metal Batteries

Advanced Science, EarlyView.
An interconnected sodiophilic Na3Sb framework embedded within a metallic Na matrix enables uniform Na deposition by homogenizing Na+ flux and providing abundant nucleation sites. Simultaneously, the regulated interface promotes the formation of a stable, NaF‐rich inorganic interphase, collectively suppressing dendrite growth and enabling highly ...

2D Vermiculite Nanosheets Encapsulated in Hydrogel Electrolyte for Shuttle‐Free and Dendrite‐Inhibited Zinc‐Iodine Batteries

Advanced Science, EarlyView.
A dual‐network hydrogel was prepared via a one‐pot method, incorporating vermiculite nanosheets as an additive. The negatively charged vermiculite nanosheets not only coordinate with zinc ions to facilitate Zn plating/stripping and suppress Zn dendrite growth, but also adsorb polyiodides to inhibit the shuttle effect, which significantly improves the ...
