Perovskite Electrocatalysts for the Oxygen Reduction Reaction in Alkaline Media
Oxygen reduction is considered a key reaction for electrochemical energy conversion but slow kinetics hamper application in fuel cells and metal-air batteries. In this review, the prospect of perovskite oxides for the oxygen reduction reaction (ORR) in alkaline media is reviewed with respect to fundamental insight into activity and possible mechanisms. For gaining these insights, special emphas...
متن کاملMetal Oxide/Pt Based Nanocomposites as Electrocatalysts for Oxygen Reduction Reaction
Fuel cell is a promising choice for clean energy because of its eco-friendly system, high energy conversion efficiency and high power density. Recently, much of the research work is focused on the system of combining metal oxides to increase the durability and surface area and to reduce the cost. In this study, among the various fabrication methods, we used the precipitation method to synthesis...
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 کاملPalladium monolayer and palladium alloy electrocatalysts for oxygen reduction.
We investigated the oxygen-reduction reaction (ORR) on Pd monolayers on various surfaces and on Pd alloys to obtain a substitute for Pt and to elucidate the origin of their activity. The activity of Pd monolayers supported on Ru(0001), Rh(111), Ir(111), Pt(111), and Au(111) increased in the following order: Pd/Ru(0001) < Pd/Ir(111) < Pd/Rh(111) < Pd/Au(111) < Pd/Pt(111). Their activity was corr...
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 ...
