The urea oxidation reaction (UOR) is an alternative anodic for hydrogen generation via water splitting. significance of UOR lies in both H2 production and the decontamination urea-containing wastewater. Commercial electrocatalysts this field are generally based on noble metals show several limitations. Bimetal–organic frameworks (BMOFs) can be excellent candidates replacement noble-metal-based catalysts beacuse their promising features, such as a tunable structure, high surface area, abundant sites electrocatalysis. In study, series nickel–cobalt BMOFs (Nix-Coy-BMOFs: x y refer to molar fraction Ni Co) were synthesized applied UOR. particular, Ni0.15Co0.85-MOF material with structure similar that its parent Co-MOF, revealed exceptional electrocatalytic performance, evidenced by low values overpotential (1.33 V vs RHE at 10 mA cm–2), TOF (0.47 s–1), Tafel slope (125 mV dec–1). At 40 cm–2 current density, also showed stability during 72 h tests. This performance NiCo-BMOF assigned synergistic effect between Co Ni, active sites, porosity, all which result increased rate due acceleration charge mass transfers. Thus, present work introduces efficient noble-metal-free energy from urea-based

The urea oxidation reaction (UOR) presents a more favorable alternative to the conventional oxygen evolution (OER) for hydrogen production due its lower thermodynamic potential. This method offers advantages over traditional approaches operating conditions and potentially costs. However, complex 6-electron transfer process in UOR limits performance. Researchers are tackling this challenge by designing advanced electrocatalysts with optimized properties, such as porosity, heterostructures, controlled defects, surface functionalization, fine-tuned electronic structures. significant progress catalyst design holds promise future of clean energy technologies. In view this, layered double hydroxides (LDHs) attracting interest their potential role electrolysis synergistic cooperation metals, flexible configuration, tunable composition unique structure. review examines recent advancements synthesis LDH-based catalysts. Beyond highlighting breakthroughs catalysts, critically stresses strategies challenges towards conversion. Moreover, comprehensive approach provides valuable forward-looking perspective on research directions.
