Asymmetric Active Sites for Boosting Oxygen Evolution Reaction
Small, 2023AbstractTransition metal‐nitrogen‐carbon materials with atomically dispersed active sites are promising catalysts for oxygen evolution reaction (OER) since they combine the strengths of both homogeneous and heterogeneous catalysts. However, the canonically symmetric active site usually exhibits poor OER intrinsic activity due to its excessively strong ...

Self-Reconstructed Metal-Organic Framework Heterojunction for Switchable Oxygen Evolution Reaction.
Angewandte Chemie, 2022Designing metal-organic framework (MOF)-based catalysts with superior oxygen evolution reaction (OER) activity and robust durability simultaneously is highly required yet very challenging due to the limited intrinsic activity and their elusive evolution ...

Discharge‐Induced Enhancement of the Oxygen Evolution Reaction
Angewandte Chemie International Edition, 2021AbstractThe fundamental understanding of the surface reconstruction induced by the applied potential is of great significance for enhancing the oxygen evolution reaction (OER). Here, we show that a previously overlooked discharge current in the low applied potential region also leads to in situ electrochemical activation of a nitrogen‐doped nickel ...

Electrocatalysis and the oxygen evolution reaction
Electrochimica Acta, 1984Abstract The oxygen evolution reaction has been investigated on a number of electrodes which are electrocatalysts for the chlorine evolution reaction, by making measurements in NaClO 4 solution. Steady state current—potential and impedance—potential measurements, obtained using automated equipment, have been used as the preferred experimental method.

The hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR) play pivotal roles in energy devices such as electrochemical water splitting, rechargeable zinc–air batteries, and fuel cells. However, the slow kinetics lead to a large overpotential being required for these three reactions because they all ...

Measuring oxygen reduction/evolution reactions on the nanoscale
Nature Chemistry, 2011The efficiency of fuel cells and metal-air batteries is significantly limited by the activation of oxygen reduction and evolution reactions. Despite the well-recognized role of oxygen reaction kinetics on the viability of energy technologies, the governing mechanisms remain elusive and until now have been addressable only by macroscopic studies.
