Interface engineering of bifunctional oxygen electrocatalysts for rechargeable Zn–air batteries

“…54,57,69 The robust immobilization of the single-atomic active sites on an unsaturation-abundant carbon platform is beneficial for modulating the electronic structure and accelerating charge/mass transfer, which finally ameliorates the electrochemical performance. 54,70 Additionally, the conductivity of catalysts can also be enhanced due to the participation of carbon materials. 71 To obtain efficient M-N/C SACs electrocatalysts, Noh et al developed a synthetic strategy based on a molecularly designed anchoring carbon platform (ACP) comprised of rich edge sites and sulfur dopants that stabilized concentrated edge-hosted single-atom M-N catalytic sites (M = Fe, Co, Ni, Cu) on carbon supports.…”

Evaluating the Oxygen Electrode Reactions of La Single-Atom Catalysts with the N/C Coordination Effect

“…Additionally, for La SACs, Yang et al successfully synthesized La@NGO by loading the La atom onto N-doped graphene oxide. The result shows that La@NGO exhibits excellent bifunctional activity and cycling stability . Nonetheless, La@NGO’s bifunctional mechanism is not well understood.…”

“…The result shows that La@NGO exhibits excellent bifunctional activity and cycling stability. 32 Nonetheless, La@NGO's bifunctional mechanism is not well understood. In addition, the calcination of the MOF materials allows the active atom La to be doped into the vacancies of the supported material, further increasing the stability of La SACs.…”
