Abstract The electrooxidation of urea holds great potential for converting from wastewater into hydrogen, contributing to environmental protection and sustainable energy production. This necessitates the development highly efficient stable catalysts oxidation reaction (UOR). In this study, a NiCoCr‐LDH/NF (nickel‐cobalt‐chromium layered double hydroxide/nickel foam) electrode is successfully synthesized via simple hydrothermal method, demonstrating excellent electrocatalytic performance with low work 1.38 V at high current density 100 mA cm −2 . situ, Raman spectra analysis revealed that incorporation chromium (Cr) facilitated generation active γ‐NiOOH species catalyst reconstruction. Density functional theory (DFT) simulations confirmed lower formation due weakened interaction O─H bonds because narrow range hybridization between O‐2p z orbitals H‐1s orbitals. introduction Cr also improved adsorption molecules its intermediates, thereby enhancing overall activity UOR. With performance, unique electronic states, coordination structures, showcases practical applications in field catalysis.

Abstract Urea‐assisted water splitting is a promising energy‐saving hydrogen (H 2 ) production technology. However, its practical application hindered by the lack of high‐performance bifunctional catalysts for urea oxidation reaction (UOR) and evolution (HER). Herein, heterostructured catalyst comprising highly active NiSe Ni 3 Se , along with conductive graphene‐coated nickel foam skeleton (NiSe‐Ni /GNF) reported. The NiSe‐Ni originates from in situ selenization foam, allowing careful regulation to ratio simply adjusting calcination temperature. Theoretical calculations charge transfer between components can optimize pathways reduce corresponding energy barriers. Accordingly, designed exhibits excellent UOR HER activity stability. Furthermore, /GNF‐based UOR‐HER electrolyzer requires only 1.54 V achieve current density 50 mA cm −2 which lower than many recent reports much 1.83 OER‐HER electrolyzers. Moreover, exhibited negligible cell voltage variation during 28‐h stability test, indicating satisfactory stability, provides new viable paradigm H production.
