Recent Progress on Fe/N/C Electrocatalysts for the Oxygen Reduction Reaction in Fuel Cells
In order to reduce the overall system cost, the development of inexpensive, high-performance and durable oxygen reduction reaction (ORR)N, Fe-codoped carbon-based (Fe/N/C) electrocatalysts to replace currently used Pt-based catalysts has become one of the major topics in research on fuel cells. This review paper lays the emphasis on introducing the progress made over the recent five years with ...
متن کاملHighly efficient electrocatalysts for oxygen reduction reaction.
Highly efficient and chemically compatible LnxSr1-xCoO3-delta (Ln = La, Sm, Gd, ...)/Co3O4 electrocatalysts for oxygen reduction reaction are presented and the very low cathode polarization resistances and excellent performances implied their promising application for developing intermediate-temperature solid oxide fuel cells (SOFCs), as well as potential application for oxygen separation membr...
متن کاملMetal corroles as electrocatalysts for oxygen reduction.
The rotating ring disk electrode method has been used to study O2 electroreduction with metal corroles. Catalysis begins at potentials that are 0.5-0.7 V more positive than the expected potential of the M(III/II) couple based on studies in non-aqueous solutions. The path of O2 reduction depends on the nature of the metal ion. Cobalt corroles promote O2 reduction to H2O2. Iron corroles catalyse ...
متن کاملFacet-dependent catalytic activity of MnO electrocatalysts for oxygen reduction and oxygen evolution reactions.
This Communication highlights the facet-dependent electrocatalytic activity of MnO nanocrystals for OERs/ORRs. The MnO(100) facets with higher adsorption energy of O species can largely promote the electrocatalytic activity.
متن کاملMechanistic Insights into the Oxygen Reduction Reaction on Metal–N–C Electrocatalysts under Fuel Cell Conditions
Fuel cells can play a crucial role in a future sustainable world; however, these devices are currently based on platinum group metals (PGMs), which is a catalyst group of materials considered as critical raw materials. Furthermore, the oxygen reduction reaction (ORR), which is more than six orders of magnitude slower than the hydrogen oxidation reaction, requires the cathode of polymer electrol...
