Enhanced Urea Oxidation Reaction by Mn‐Doped Nickel Hydroxide From Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mn incorporation modifies the hydroxide structure and modulates the electronic properties of the Ni centers, promoting the formation of catalytically active NiOOH species. Mn dopants induce a favorable electronic effect but do not directly participate in the UOR mechanism, enhancing the overall urea oxidation rate and resulting in increased hydrogen ...

Bidentate‐Ligand Molecular Bridge in NiFe‐LDH as a Dynamic Proton Relay and Electronic Modulator to Enhance the Oxygen Evolution Reaction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
By introducing 4‐chlorobenzoic acid ligands into the interlayer of NiFe‐LDH, the carboxyl and Cl groups on either side are respectively bonded to nearby Fe atoms, yielding a stable Bridge‐Linked structure. The strong electron interaction between the ligands and metal ions suppresses metal ion leaching during the reaction process, thereby maintaining ...

Amide Methylation Empowers Concentrated Hydrogel Electrolytes for Wide‐Temperature Flexible Aqueous Sodium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An aprotic poly(N,N‐dimethylacrylamide) matrix provides free C=O sites for strong ion solvation, establishing a stable and homogeneous gel phase. This unique polymer network effectively reduces H2O activity, enabling highly concentrated gel electrolytes for high‐voltage, wide‐temperature, and flexible aqueous sodium‐ion batteries.
