Synergistically Accelerating Zn2+ Transport and Desolvation Through Cation‐Deficient Ion Channels in High‐Performance Zn Metal Batteries

Carbon Energy, EarlyView.
The novel ITO protective layer enables ultra‐stable Zn metal anodes. By synergistically accelerating Zn2+ desolvation and Zn2+ transport via its unique structure, the ITO layer suppresses dendrites and side reactions. This results in exceptional stability for over 6000 h at 2 mA cm–2 and stable operation in Zn ||MnO2 full‐cell configurations.

Anchoring Monolayer TiOx Nanosheets on Gold Nanoparticles Enhances Catalytic Activity for CO Oxidation Depending on the Type of Support

Chemistry – A European Journal, EarlyView.
Monolayer TNS cover Au/SiO2 and Au/CeO2 surfaces, forming Au–TiOx contact structure that serve as active sites for CO oxidation, thereby significantly improving catalytic activity. On Au/SiO2, the Au–TiOx interface was generated through TNS adsorption and calcination, while TNS adsorption solely promoted the Au–TiOx interface formation on Au/CeO2.

Design of a Novel CeW/Fe‐TiO2 Catalyst With High Oxygen Vacancy for Enhancing the Reactivity and SO2 Resistance in Low‐Temperature NH3‐SCR Reaction

EcoEnergy, EarlyView.
Fe3+ was introduced into the TiO2 lattice using the hydrothermal method, and low‐valent cations replaced part of Ti4+ to generate oxygen vacancies within the Fe‐Ov‐Ti unit, resulting in CeW/Fe‐TiO2 catalysts with oxygen‐deficient structures. Compared with CeW/TiO2 catalyst, the increase in oxygen vacancy content significantly improved the catalytic ...
