TL;DR: In this article, the authors developed an approach to control dendrite growth by coating the separator with functionalized nanocarbon (FNC) with immobilized Li ions.

TL;DR: Characterization by multiple techniques shows that all Fe–N4 sites formed via this approach are gas-phase and electrochemically accessible and have an active site density of 1.92 × 1020 sites per gram with 100% site utilization.

TL;DR: In this article, a facile strategy to covalently graft p-phenyl SO3H or pphenyl NH2 groups onto the graphene surface was developed to not only facilitate the homogeneous distribution of Pt nanoparticles on the surface of graphene supports and reduce the Pt average particle size but also strengthen the interaction of the Pt atoms with the functional groups and, consequently, minimize t...

TL;DR: This work unravels the evolution pathway of precursors to ORR-active catalyst comprised exclusively of single atom Fe1(II)-N4 sites via in-temperature X-ray absorption spectroscopy and verifies the vapor phase single Fe atom transport mechanism via "non-contact pyrolysis".

TL;DR: The development of PGM-free and iron-free catalysts for the kinetically sluggish oxygen reduction reaction (ORR) is crucial for proton-exchange membrane fuel cells as mentioned in this paper.
