Dynamic stability of oxygen evolution

In a study published in Nature Energy, researchers investigated the mechanisms that drive stability and activity in materials during oxygen evolution reactions. This insight will guide the design of materials for electrochemical fuel production.

Scientific Achievement

Dynamically stable iron (Fe), as a result of dissolution and redeposition at the electrolyte/host interface, provides a general description for O2 evolution activity and stability.

Significance and Impact

Dynamic stability overcomes the limitations imposed by the thermodynamic instability of oxide materials and demonstrates new concepts of stability”.

Research Details

  • Design of a new (electro)chemical interface was validated by an active site/host pair using a well controlled hydr(oxy)oxide cluster.
  • In situ and ex situ ICP-MS, in combination with isotope labeling, confirm dynamic exchange of Fe active sites.
