Hydrogen plays a vital role in the global shift toward cleaner energy solutions, with water electrolysis standing out as one of most promising techniques for generating hydrogen. Despite its potential, oxygen evolution reaction (OER) involved this process faces significant challenges, including high overpotentials and slow rates, which underscore need advanced electrocatalytic materials to enhance efficiency. Noble metal catalysts are effective but expensive, so transition-metal-based electrocatalysts like nickel-cobalt layered double hydroxides (NiCo LDHs) have become alternatives. In research, series NiCo LDH doped Fe, Mn, Cu, Zn were effectively produced using one-step hydrothermal technique. Among catalysts, Fe-doped exhibited OER activity, achieving lower overpotential (289 mV) at current density 50 mA/cm2, was far better than 450 mV undoped LDH. The Mn-, Cu-, Zn-NiCo LDHs also 414 mV, 403 357 respectively, density. had 3D nanoflower structure, increasing surface area reactant adsorption. electrochemically active (ECSA), indicated by double-layer capacitance (Cdl), larger samples. Cdl value 3.72 mF/cm2, significantly surpassing 0.82 mF/cm2 These changes improved charge transfer optimized kinetics, enhancing overall performance. This study offers contributions development efficient OER, advancing understanding key design principles enhanced catalytic
