Advanced Energy Materials, EarlyView.Aliovalent B‐site substitution with Sn2+ in lead‐free perovskite, Cs3Bi2Br9, is employed to simultaneously induce lattice contraction and bromine vacancy through charge imbalance and ionic radius mismatch. The resulting structural distortion modulates the electronic structure and improves charge separation, leading to enhanced visible‐light‐driven CO2 ...

Angewandte Chemie, EarlyView.An electron bridge strategy is developed to regulate charge polarization in Pd1 and Ni1 dual single‐atom sites, promoting CO2 reduction, nitrate reduction, and C–N coupling simultaneously. The resulting catalyst achieves efficient urea electrosynthesis with high activity and record durability over 1700 h.

Advanced Energy Materials, EarlyView.This work introduces a CeHP‐enabled multifunctional matrix‐activated electrode (MME) for high‐temperature PEM fuel cells, forming an electrochemically and mechanically functional matrix within the catalyst layer. The design increases peak power density by 38% and reduces voltage decay by 62% at 240 °C, while using only 40% of the Pt loading of a ...

Angewandte Chemie, EarlyView.An interfacial ion‐specific gating strategy shifts membrane design from ion diffusion within ion‐exchange channels to ion partitioning at the membrane–electrolyte interface, thereby decoupling selectivity from conductivity. The strategy underscores the pivotal yet underexplored role of the membrane–electrolyte interface, providing a broadly applicable ...

Electro‐Organic Synthesis at a Stable Oil/Water/Solid Three‐Phase Interface Reactor
Angewandte Chemie, EarlyView.A porous membrane electrode (PME) reactor is developed to promote oil/water/solid three‐phase interfacial contact for electro‐organic synthesis. By promoting the formation of an oil/water interfacial region within or near an amphiphilic catalytic layer, the reactor enables efficient conversion of water‐insoluble organic reactants in aqueous ...

Advanced Energy Materials, EarlyView.We demonstrate how improved electrochemical performance during water electrolysis is achieved when a porous transport electrode (PTE) is coupled with a traditional catalyst coated membrane (CCM). Using operando neutron radiography, a more homogenous water distribution near the catalyst layer‐membrane interface is revealed in PTE‐based designs due to ...

Boosting Charge Storage in Ferri/Ferrocyanide‐Based Alkaline Redox Flow Batteries
Angewandte Chemie, EarlyView.By modifying the solvation environment, cation engineering through Li+ substitution of traditional K+ or Na+ boosts the alkaline solubility of the ferri/ferrocyanide catholyte redox couple, providing a viable pathway to overcome the long‐standing challenge of energy density limitations for aqueous redox flow batteries (RBFs).

Advanced Energy Materials, EarlyView.A positively polarized ferroelectric β‐pvdf layer incorporating fluorinated boron nitride nanosheets (PPFBN) establishes a strong internal field that promotes Li+ transport toward the anode while suppressing the migration of polysulfide anions. In addition, its intrinsically low polysulfide affinity helps preserve protective‐layer functionality ...
