The Haber Bosch Catalyst from Solid state Chemistry to Mesotechnology
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 ...

This work presents a tailored solid‐state route to enhance DRX fluorination and electrochemical performance. Using unconventional precursors, Li6MnO4, MnF2, and TiO2, prevents Mn‐based intermediates, which do not accommodate fluorines, enabling the formation of highly fluorinated DRX with a composition of Li1.23Mn0.40Ti0.37O2−yFy (y = 0.29–0.34 ...

Through comprehensive operando and postmortem investigations, it is shown that the single‐crystalline LiNiO2 cathodes, even when cycled under stressful conditions that expedite O loss, can retain their bulk redox stability. The predominant cathode degradation mode is the growth of a densified surface layer, which severely impedes Li‐ion diffusion and ...

Achieving High Energy Density in Aqueous Zinc‐Ion Batteries
Aqueous zinc‐ion batteries (AZIBs) offer high safety, cost‐effectiveness, and environmental benefits, yet achieving high energy density remains a challenge. This review explores advances in cathodes, zinc anodes, separators, and electrolytes to enhance energy density. It also discusses scalability and future directions, highlighting AZIBs potential for
