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

open access: yesEcoEnergy, 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)

Oxygen‐Vacancy‐Engineered Ru–V Dual Sites in InVO4 for Synergistic Photocatalytic N2 Activation and Reactive Hydrogen Supply

open access: yesEcoEnergy, EarlyView.
This study developed a catalyst composed of Ru nanoparticles directionally anchored at the oxygen vacancies of indium vanadate. Oxygen vacancy not only forms unsaturated V sites but also serves as an anchoring site for Ru nanoparticles, establishing a stable Ru‐V coordination structure through electronic metal–support interactions.
