Zn-NO3- batteries can generate electricity while producing NH3 in an environmentally friendly manner, making them a very promising device. However, the conversion of NO3- to involves proton-assisted 8-electron (8e-) transfer process with high kinetic barrier, requiring high-performance catalysts realize potential applications this technology. Herein, we propose heterostructured CoO/CuO nanoarray electrocatalyst prepared on copper foam (CoO/CuO-NA/CF) that electrocatalytically and efficiently convert at low achieves maximum yield 296.9 μmol h-1 cm-2 Faraday efficiency (FE) 92.9% -0.2 V vs. reversible hydrogen electrode (RHE). Impressively, battery based monolithic CoO/CuO-NA/CF delivers 60.3 cm-2, FENH3 82.0%, power density 4.3 mW cm-2. This study provides paradigm for catalyst preparation energy-efficient production simultaneously generating electrical energy.

Abstract Compared with the traditional electrolysis of water to produce hydrogen, urea‐assisted hydrogen has significant advantages and received extensive attention from researchers. Unfortunately, urea oxidation reaction (UOR) involves a complex six‐electron transfer process leading high overpotential, which forces researchers develop high‐performance UOR catalysts drive development splitting. Based on mechanism literature research, this review summarizes strategies for preparing highly efficient catalysts. First, is introduced characteristics excellent are pointed out. Aiming at this, following modulation proposed improve catalytic performance based summarizing various literature: 1) Accelerating active phase formation reduce initial potential; 2) Creating double sites trigger new mechanism; 3) adsorption promoting C─N bond cleavage ensure effective conduct UOR; 4) Promoting desorption CO 2 stability prevent catalyst poisoning; 5) electron overcome inherent slow dynamics 6) Increasing or surface area. Then, application in electrochemical devices summarized. Finally, current deficiencies future directions discussed.

In this study, we prepared amorphous iron-cobalt oxide through the dealloying of trimetallic FeCoAl, showing excellent performance in both urea oxidation and hydrogen evolution reactions (UOR HER) alkaline seawater. The catalyst demonstrated stable UOR HER activity during long-term operations due to abundant active sites oxygen vacancies. required applied potentials 1.52 -0.185 V yield 100 mA cm-2 for HER, respectively. Moreover, when used as cathode anode, electrolyzer a working voltage 1.68 urea-assisted production.
