Why weak-binding M–N–C catalysts defy expectations in oxygen reduction reactions
These findings, now published in the Journal of the American Chemical Society, could revolutionize the design of ... M–N–C Single-Atom Catalysts Possess Anomalously High Oxygen Reduction ...

Lesson 4.4: Energy Levels, Electrons, and Covalent Bonding
When two hydrogen atoms and an oxygen atom get close enough, the electron from each atom feels an attraction from the protons in the other atom's nucleus. This attraction pulls the atoms together. The ...

Lesson 5.1: Water is a Polar Molecule
The electron cloud model shows that electrons are not shared equally in the water molecule. Electrons are a bit more attracted to the oxygen atom than they are to the hydrogen atoms. This makes the ...

Regulating atomic Fe-Rh site distance for efficient oxygen reduction reaction
In a study published in the journal Science China Chemistry, the authors systematically design and investigate the site-distance effect of Fe-Rh atom catalysts (Fe-Rh x @NC) supported by N-doped ...
