Urea oxidation reaction (UOR) is one of the potential routes in which urea-rich wastewater used as a source energy for hydrogen production. Metal–organic frameworks (MOFs) have promising applications electrocatalytic processes, although there are still challenges identifying MOFs' molecular regulation and obtaining practical catalytic systems. The current study sought to synthesize [Zn6(IDC)4(OH)2(Hprz)2]n (Zn-MOF) with three symmetrically independent Zn(II) cations connected via linear N-donor piperazine (Hprz), rigid planar imidazole-4,5-dicarboxylate (IDC3–), −OH ligands, revealing 3,4T1 topology. optimized noble-metal-free Zn0.33V0.66-MOF/NF electrocatalysts show higher robustness performance compared those parent Zn monometallic MOF/NF electrode other bimetallic MOFs different Zn–V molar ratios. low 1.42 V (vs RHE) at 50 mA cm–2 1.0 M KOH 0.33 urea required by developed Zn0.33V0.66-MOF makes its application UOR more feasible. availability exposed active sites, ion diffusion path, conductivity result from distinctive configuration synthesized electrocatalyst, highly stable capable synergistic effects, consequently enhancing desired reaction. research contributes introducing practical, cost-effective, sustainable solution decompose produce hydrogen.

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.
