TL;DR: The catalyst's outstanding performance may have resulted from the ultrahigh dispersion of Pt (several atomic layers coated on the nitride nanoparticles), and the excellent stability/durability may have been due to the good stability of nitride and synergetic effects between ultrathin Pt layer and the robust TiNiN support.

TL;DR: In this paper, the authors explored the limitations for early transition-metal nitrides as competitive catalysts in the view of O2 dissociation, finding that the limitations include insufficient d electrons (in the case of ScN, TiN, and VN) and unsuitable surface geometric structure, both of which can result in no O 2 dissociation on early-transition-metal Nitrides, and proposed a strategy to enhance its ORR activity by enriching its d electrons through doping with 3d transition metals.

TL;DR: In this paper, a binary transition metal nitride (BTMN) catalyst was proposed, which exhibited excellent activity towards the oxygen reduction reaction (ORR) in an alkaline medium and good ORR activity in an acidic medium.

TL;DR: In this article, a core-shell structured low-platinum catalysts with well-dispersed inexpensive titanium copper nitride nanoparticles as cores and atomic platinum layers as shells exhibiting high activity and stability for the oxygen reduction reaction is successfully developed.
