Abstract The economically unfeasible electrochemical breakdown of water is linked to the production materials with low overpotential using a simple method. study demonstrates fabrication and use samarium oxide (Sm 2 O 3 ) on carbon nanotubes (CNTs) as an effective long‐lasting electrocatalyst for oxygen evolution reaction (OER). X‐ray diffraction analysis confirms Sm embedded CNTs /CNTs) phases 0.052 nm lattice strain, while scanning electron microscopy structural shows ball‐like shape 78 average particle size. synthesized catalyst performs well, attaining current density 10 mA cm −2 having onset potential 1.33 V versus reversible hydrogen electrode (RHE). In contrast CNT, which exhibit higher overpotentials 311 342 mV corresponding Tafel slopes 62 83 dec −1 , respectively, ‒CNT has slope 38 lower 276 mV. With more than 50 demonstrated remarkable stability over 180 h. impedance spectroscopy attributed robust ionic conductivity K⁺ ions, their small hydration sphere, reduced R ct value 3.4 Ω. composite long‐term OER electrocatalysis substitute been through promising results.
