The upsurging of cost-effective de novo electrocatalysts through the operando electro-oxidation approaches holds great promise for scalable production green energy in pursuit sustainability. This work introduces an reconstitution strategy producing a smart electrocatalyst, cobalt "oxyhydroxide" derived from newly designed 2D cobalt(II) metal–organic framework (NBU-4) directly grown on nickel foam (NF), NBU-4/NF@CoOOH. NBU-4/NF@CoOOH, exhibits outstanding overpotential 76 mV hydrogen evolution reaction and 336 oxygen to achieve current density 10 mA/cm2 with remarkable Faradaic efficiencies 97.1 93.4%, respectively, 1 M aqueous KOH. Unveiling bifunctionality NBU-4/NF@CoOOH as cathode anode overall water splitting KOH, low voltage 1.65 V was needed obtain density. Nonetheless, displayed excellent stability 12 h evidenced chronopotentiometry recorded at mA/cm2. bifunctional electrocatalytic performance electrocatalyst 50 is attributed unique hexagonal nanosheet morphology microporous structure zigzag flow channels NF, facilitating faster kinetics Co3+ Ni2+ dual sites synergism.

This study aims to determine the electrochemical performance of FeWO4 (Fe), NiFeOOH (Ni), and FeWO4/NiFeOOH (FeNi) electrodes in 0.1 M Na2SO4 NaOH electrolytes, highlighting impact SO42− OH− ions. Nyquist analysis demonstrated that electrode had lowest charge transfer resistance, indicating superior transport capacitive over individual electrodes. In Na2SO4, ions stabilized double-layer capacitance enhance ionic mobility. Conversely, NaOH, highly conductive mobile significantly improved diffusion, making more effective for applications. Tafel revealed better kinetics greater energy efficiency with composite excelling both electrolytes. Linear voltammetry showed a synergistic interaction between NiFeOOH, achieving photocurrent density 6.70 mA·cm−2 under illumination, an 830.56% increase Na2SO4. Additionally, exhibited longer electron lifetimes than attributed smaller radius higher diffusion coefficient Pulsed notable improvements generation stability NaOH. These findings indicate is efficient stable material advanced technologies, providing optimal conditions.

Furthermore, we integrated these catalysts into practical applications, including metal‐air batteries, lithium‐sulfur non‐enzymatic glucose sensors. To further demonstrate the innovative contributions work, systematically compare it with advanced work by other groups. Based on findings performance benchmarking analyses, identify critical challenges that must be addressed advance MOFs‐based toward next‐generation conversion sensing.
