Regulating Uniform Zinc Deposition via Covalently Tethered Imidazolium Cations in Polyacrylamide Hydrogel Electrolytes for Stable Aqueous Zinc Batteries

Advanced Energy Materials, EarlyView.
A positively charged polyionic liquid hydrogel electrolyte is developed for highly stable aqueous zinc‐ion batteries. Imidazolium cations anchored on the polymer framework create a dynamic electrostatic shield at the anode interface. This active layer effectively repels water molecules and guides uniform zinc deposition, thereby suppressing dendrite ...

MXene‐Derived Highly Oriented TiN Enables Ta3N5 Photoanodes for Transmission‐Mode Bias‐Free Solar Water Splitting

Advanced Energy Materials, EarlyView.
This work reports 2D MXene‐derived TiN thin films with (111)‐preferred orientation for transparent Ta3N5 photoanodes, demonstrating effective electron transfer behavior. All‐nitride electron‐collection architecture based on MXene‐derived TiN and n‐GaN resolves a long‐standing materials bottleneck between photocarrier transport and light transmission in

Microenvironment Engineering as a Design Principle for Suppressing Catalyst Metal Loss

Angewandte Chemie, EarlyView.
Under ionomer‐containing microenvironments, nonporous carbon supports enhance the retention of dissolved platinum ions, whereas porous carbon supports promote pore‐confined redeposition and mitigate net platinum loss. ABSTRACT Stability losses in platinum electrocatalysts arise from dissolution, redeposition, and restructuring processes that are ...
