Selectively anchoring single atoms on specific sites of supports for improved oxygen evolution

Zhirong Zhang et al.

Summary: This study investigates the influence of different anchoring sites on the oxygen-evolving electrocatalysis by selectively anchoring iridium single atoms onto different positions on a defective CoOOH surface. The results show that the electronic interaction between the single-atom iridium and the support modifies the electronic structure of the active center in Ir-1/T-O-CoOOH, while a hydrogen bonding stabilizes the intermediates and lowers the energy barrier in Ir-1/V-O-CoOOH. This indicates that the homogeneity of single-atom catalysts is not only determined by their structures, but also by the localized coordination environments.

Promoting nickel oxidation state transitions in single-layer NiFeB hydroxide nanosheets for efficient oxygen evolution

Yuke Bai et al.

Summary: This article presents a synthesis method for single-layer NiFeB hydroxide nanosheets and demonstrates the effectiveness of electron-deficient boron in promoting the formation of high-oxidation-state Ni for improved oxygen evolution activity. Experimental results show that the incorporation of boron into a NiFe hydroxide can cause a cathodic shift of the Ni2+(OH)(2) -> Ni3+delta OOH transition potential and reduce the energy barriers for the reaction. As a result, the catalyst achieves a current density of 100 mA cm(-2) in 1 M KOH and is among the best Ni-based catalysts for this reaction.

Likun Gao et al.

Summary: Recent advancements in the development of cost-effective and high-efficiency transition metal-based electrocatalysts have led to a better understanding of the dynamic reconstruction of surface structures during electrocatalytic water oxidation, especially the anodic oxygen evolution reaction (OER). Through operando and in situ techniques, it has been found that electrocatalysts undergo surface reconstruction to form actual active species during OER in alkaline solution. By exploring issues such as initiators for surface reconstruction and establishing relationships between structure, composition, and electrocatalytic activity, progress has been made in the rational manipulation of in situ catalyst surface reconstruction for the development of high-efficiency electrocatalysts.
