Understanding of Oxygen Redox in the Oxygen Evolution Reaction

Advanced Materials, 2022
AbstractThe electron‐transfer process during the oxygen evolution reaction (OER) often either proceeds solely via a metal redox chemistry (adsorbate evolution mechanism (AEM), with metal bands around the Fermi level) or an oxygen redox chemistry (lattice oxygen oxidation mechanism (LOM), with oxygen bands around the Fermi level).

The roles of oxygen vacancies in electrocatalytic oxygen evolution reaction

Nano Energy, 2020
Abstract The efficiency of many rechargeable energy storage technologies and hydrogen production from water splitting is limited by the oxygen evolution reaction (OER) due to its sluggish kinetics. Understanding the characteristics of the material that affect OER activity is of paramount importance for the development of high-efficiency ...

Bifunctional Catalysts for Reversible Oxygen Evolution Reaction and Oxygen Reduction Reaction

Chemistry – A European Journal, 2020
AbstractMetal‐air batteries (MABs) and reversible fuel cells (RFCs) rely on the bifunctional oxygen catalysts for oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). Finding efficient bifunctional oxygen catalysts is the ultimate goal and it has attracted a great deal of attention.

Discharge‐Induced Enhancement of the Oxygen Evolution Reaction

Angewandte Chemie International Edition, 2021
AbstractThe 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 ...

Recent innovations of silk-derived electrocatalysts for hydrogen evolution reaction, oxygen evolution reaction and oxygen reduction reaction

International Journal of Hydrogen Energy, 2021
Abstract Numerous researches have proved that heteroatom-doping, especially N-doping, is able to enhance the electrocatalytic performance for carbon materials toward water electrolysis and oxygen reduction reaction. Hence, the production of N-doped carbon materials from cheap and earth-abundant precursor resources such as biomass materials has great ...

Oxygenated Carbon Electrocatalysts for Chlorine Evolution Reaction

Journal of the American Chemical Society
The chlor-alkali process plays an irreplaceable role in global chemical industry, but relies heavily on RuO2 (or IrO2)/TiO2-based dimensionally stable anodes, hindering sustainability and new applications. We report a facile oxygenation activation approach to create apt oxygen groups on commercial carbon black and carbon cloth.
