Intermolecular Energy Gap-Induced Formation of High-Valent Cobalt Species in CoOOH Surface Layer on Cobalt Sulfides for Efficient Water Oxidation

Na Yao et al.

Summary: This study reports a method for electrochemical synthesis of amorphous CoOOH layers on the surface of various cobalt sulfides (CoS alpha) and identifies the phenomenon that reducing the intermolecular energy gap can accelerate the formation of OER-active high-valent Co4+ species. The combination of electrochemical and spectroscopic approaches reveals that Co species in the CoOOH/Co9S8 sample are more readily oxidized compared to other samples. This work provides a new design principle for transition metal-based OER electrocatalysts.

Construction of Fe-doped NiS-NiS2 Heterostructured Microspheres Via Etching Prussian Blue Analogues for Efficient Water-Urea Splitting

Shoushuang Huang et al.

Summary: Efficient and robust Fe-doped NiS-NiS2 heterostructured microspheres were successfully synthesized for electrocatalytic water-urea splitting. The microspheres, constructed by mesoporous nanoplates, provide large surface areas, high structural void porosity, and accessible inner surface, enabling more redox reaction centers, improved structural robustness, and facilitated mass diffusion and charge transport. Density functional theory simulations show that Fe-doping enhances the conductivity of nickel sulfides, while the NiS-NiS2 heterojunctions optimize the adsorption free energy of intermediates, resulting in a low overpotential and high electrocatalytic activity.
