A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

EcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

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 ...

Ni–Zn–Ga Alloy for Weak Sunlight‐Driven Methanol Production From CO2 and H2O at Ambient Pressure

EcoEnergy, EarlyView.
The Ni–Zn–Ga ternary alloy‐assisted photothermal CO2 hydrogenation system coupled with photovoltaic water splitting could convert CO2 and H2O into methanol with a production rate of 709 μmol g−1 h−1 under natural sunlight irradiation. ABSTRACT The sunlight‐driven artificial photosynthesis that converts CO2 and H2O into methanol is a promising approach ...

Toward Single‐Crystal Upcycling of Degraded Lithium‐Ion Battery Cathodes

EcoEnergy, EarlyView.
This review first summarizes the degradation mechanisms of polycrystalline cathodes, emphasizing the role of grain boundaries and rock‑salt phase formation. It then highlights the main optimization pathways (surface reconstruction, rapid structural repair, PC‑to‑SC transformation, and interface engineering) and the three conversion methods (SSU, MSAU ...
