Abstract Investigating advanced electrocatalysts is crucial for improving the efficacy of water splitting to generate environmentally friendly fuel. The discovery highly effective electrocatalysts, capable driving oxygen evolution reaction (OER) and urea oxidation (UOR) in urea‐alkaline environments, pivotal advancing large‐scale hydrogen production. This study aims introduce a new method that involves creating nanosheets high‐loading iridium single atoms embedded manganese‐containing nickel oxyhydroxide matrix (Ir@Mn─NiOOH). These nanostructures are derived from self‐supported hydrate pre‐catalyst grown on foam then activated through electrochemical etching pretreatment. Ir@Mn─NiOOH nanoarchitecture displays outstanding electrocatalytic activity, having low overpotential just 258 mV potential 1.319 V (at 10 mA cm −2 ) OER UOR, respectively. Such extraordinary catalytic characteristics mainly owing strong synthetic electronic interaction between Ir Mn─NiOOH, which can change its boost sites. research presents way produce exceptionally efficient catalysts by adding synergistic effect complex multi‐electron processes.
