The atomic-scale local structures of ruthenium oxide were precisely engineered through controllable manipulation of oxygen vacancies (O v) via high-vacuum annealing. The optimized Ru-Ru and adjacent ...

Researchers directly observed bulk oxygen spillover in catalysts for the first time, revealing that a catalyst's interior can ...

Fe-N 4 is a typical active site in Fe-N/C catalysts with maximum atomic utilization and a well-defined structure. However, its high symmetry limits further electronic structure optimization and ...

Scientists have captured the first-ever image of individual atomic oxygen dissolved in water, using an advanced laser approach that reveals previously unknown behaviors of this highly reactive species ...

Scientists found that tweaking nitrogen arrangement around single cobalt atoms dramatically improves oxygen reduction, offering a blueprint for better fuel cell catalysts. Single-atom ...
