Understanding the Structural Evolution of a Nickel Chalcogenide Electrocatalyst Surface for Water Oxidation

Umanga De Silva et al.

Summary: This study investigated the evolution of the active surface composition for nickel-selenide and -telluride-based electrocatalysts by intentionally creating nickel-oxide-coated surfaces. The results confirmed the stability of the catalytically active chalcogenide surfaces in alkaline medium, providing evidence that the surface evolves into a mixed anionic (hydroxo)chalcogenide surface. The study also highlighted the significant differences in electrochemical properties between oxide-coated, selenide, and telluride surfaces, emphasizing the importance of understanding the composition changes in chalcogenide surfaces using electrochemical properties.

Summary: Metal telluride nanocatalysts have been widely used in catalysis, but there are limited examples of their application in electrocatalytic water oxidation. In this study, Te-doped Fe-based catalysts were successfully synthesized using chemical vapor deposition and electrodeposition methods, with the latter showing better electrocatalytic performance in alkaline electrolyte. The electrochemical study confirmed that the residual Te in the electrodeposited FeTex played a role in promoting the catalytic activity for electrocatalytic water oxidation.

Why the optimum thermodynamic free-energy landscape of the oxygen evolution reaction reveals an asymmetric shape

Kai S. Exner

Summary: The development of OER electrocatalysts is driven by thermodynamic considerations, aiming for a symmetric free-energy landscape but often encountering linear scaling relationships. Recent studies show that an asymmetric rather than symmetric free-energy landscape may better correspond to the thermodynamic ideal, leading to a shift in mindset for material discovery in OER.

Why the breaking of the OOH versus OH scaling relation might cause decreased electrocatalytic activity

Kai S. Exner

Summary: This paper discusses the efforts made in the past decade to break the OER scaling relation, highlighting the challenges in improving OER material design. Introducing kinetics into the thermodynamics-based concept of scaling relations indicates that breaking the relation may reduce electrocatalytic activity, suggesting the need to advance the theoretical description of the OER in different directions, such as investigating competing mechanistic pathways or microkinetic considerations.
