Hydrazine‐Mediated Thermally Assisted Photocatalytic Ammonia Decomposition Over Layered Protonated Perovskites

Advanced Science, EarlyView.
Herein, a new catalyst, protonated layered perovskite HPrNb2O7, is presented, which exhibits exceptional photocatalytic activity for solar‐driven ammonia decomposition. Its unique structure facilitates the generation of active sites while extending charge carrier lifetime with input thermal energy. Abstract Photocatalytic ammonia decomposition offers a

Solvated PbI2 Clusters Preceding the Crystallization of Lead Halide Perovskites–a UV/VIS In Situ Study

Advanced Electronic Materials, EarlyView.
This work focuses on the crystallization dynamics in lead iodide perovskite films: In situ UV absorption spectroscopy reveals a PbI2‐DMF solvated (PDS) phase before nucleation, influencing perovskite formation. PDS clusters act as nucleation seeds, linking precursor solution concentration to crystallization.

The Haber Bosch Catalyst from Solid state Chemistry to Mesotechnology

Advanced Energy Materials, EarlyView.
A comprehensive, multi‐scale, multi‐modal study of the structural diversity of a technical multi‐promoted Haber Bosch catalyst for ammonia synthesis is provided. The different contributions of ammonia Fe are revealed and the presence of cement phases that have yet not been incorporated into discussions on the function of this catalyst system is shown ...

Connecting Local Structure, Strain and Ionic Transport in the Fast Sodium Ion Conductor Na11+xSn2+xP1−xS12

Advanced Energy Materials, EarlyView.
Substitution by larger polyanions in the fast sodium ion conductor Na11+xSn2+xP1−xS12 leads to inhomogeneities in the local structure which induces micro strain. The observed strain correlates with higher local diffusivities at room temperature and a lowering of the activation barriers for local ionic jumps which is explained by a widening of ...

Visualizing the Dynamic Wetting and Redistribution of Electrolyte in Lean‐Electrolyte Lithium‐Sulfur Pouch Cells via Operando Neutron Imaging

Advanced Energy Materials, EarlyView.
The inhomogeneous electrolyte wetting in lean‐electrolyte lithium–sulfur pouch cells is visualized by operando neutron tomography non‐destructively. Real‐time observation of electrolyte in different layers of pouch cells reveals different electrolyte wetting behaviors under various cell status, including cell rest, states of discharge, and charge at ...
