Abstract Understanding the metal–oxygen covalency in transition metal oxides lays groundwork for fine‐tuning their activity toward oxygen evolution reaction (OER). Herein, a large‐scale synthesis of cobalt oxide heterostructure nanowires encapsulated nitrogen‐doped carbon (CoO/Co 3 O 4 @NC) is reported and reveals correlation Co–O with OER activity. Operando characterizations reveal that surfacial Co species are partially oxidized to higher‐valence CoO 2 , which serve as active sites OER. Theoretical calculations further disclose charge redistribution at CoO/Co interface, effectively enhancing electrochemical conductivity kinetics. Additionally, moderate found promote stronger interaction intermediates, reducing energy barrier improving Consequently, @NC achieve superior an overpotential 263 mV 10 mA cm −2 . Moreover, electrocatalyst preparation could be easily scaled up gram‐level per batch. This work deepens fundamental understanding about role OER, demonstrates cost‐effective larger‐scale practical applications.

Urea-assisted water electrolysis offers an effective strategy to significantly lower the cell voltage required for hydrogen production, while development of efficient and earth-abundant bifunctional electrocatalysts has attracted considerable attention. Here, we present crystalline cobalt phosphite as a electrocatalyst, facilitating both cathodic production anodic urea oxidation. Surface reconstruction is demonstrated, leading formation oxyhydroxides, which act active sites electrocatalysis. Notably, achieving current density 10 mA cm–2 requires ultralow potentials −59 mV reaction 1.302 V reaction. Additionally, overall 1.376 achieved sustain same in two-electrode hybrid system, considerably than that traditional splitting (1.577 V). This newly developed electrocatalyst shows great promise future energy-saving urea-related wastewater treatment applications.
