Cobalt (II) oxide nanosheets with rich oxygen vacancies as highly efficient bifunctional catalysts for ultra-stable rechargeable Zn-air flow battery

Mingjie Wu et al.

Summary: The development of highly efficient bifunctional catalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is crucial for rechargeable Zn-air batteries. Cobalt (II) oxide (L-CoO) nanosheets with hierarchical nanostructures were grown on stainless steel (SS) substrate via a simple heat treatment, showing superior ORR/OER activity and stability in the rechargeable Zn-air flow battery for over 1000 hours. X-ray absorption spectroscopy (XAS) and X-ray photoelectron spectroscopy (XPS) were used to uncover the reasons behind the excellent bifunctional catalytic performance of this catalyst, with operando XAS revealing the atomic-scale structures as support for the stability of L-CoO during electrocatalytic operation.

Constructing the CoO/Co4N heterostructure with an optimized electronic structure to boost alkaline hydrogen evolution electrocatalysis

Na Yao et al.

Summary: The development of cost-efficient electrocatalysts with high performance and durability for the alkaline HER remains a big challenge. In this study, a CoO/Co4N heterostructure electrocatalyst is reported to exhibit remarkable HER performance in alkaline electrolytes. Density functional theory calculations and experimental results suggest that enhanced H2O adsorption, optimized hydrogen adsorption, and promoted H-ad diffusion contribute to the outstanding HER activity with a relatively low overpotential.
