<p>The doping of Ru and Fe into β-MnO₂ improves the conductivity which aids in better electrocatalytic OER performance. Synergetic effect of Ru/Fe on β-MnO₂ framework is highly beneficial to balance the stabilizing structures. For OER in alkaline media, we have therefore synthesized β-MnO₂ and doped Ru@β-MnO₂, Fe@β-MnO₂, and dual doped Ru-Fe@β-MnO₂. The OER overpotentials were 550 mV, 310 mV, 290 mV, and 260 mV at a current density of 10&#xa0;mA cm^− 2, while the Tafel slope values in 1&#xa0;M KOH were 126 mV dec^− 1, 107 mV dec^− 1, 100 mV dec^− 1, and 86 mV dec^− 1, respectively. When Fe@β-MnO₂ and Ru@β-MnO₂ are co-doped, the XPS shows that the binding energy shifts to a lower value, confirming the partial reduction of Mn⁴⁺ to Mn³⁺. However, when Ru-Fe@β-MnO₂ is co-doped, the Mn 2p peaks return to higher binding energies, like the β-MnO₂. The observed shifts in binding energies implies a dynamic equilibrium in the MnO₂ lattice leads to electron donation. The Co-doping introduce additional electrons into the MnO₂ lattice, reducing Mn⁴⁺ to Mn³⁺. This interplay suggests a self-regulating mechanism where the Mn oxidation state adjusts in response to the electronic effects of the dopants, maintaining the structural and electronic integrity of the MnO₂ lattice. Further, this co-doped Ru-Fe@β-MnO₂ nanoarrays demonstrated good long-term stability for 15&#xa0;h, with no distinct changes observed in its chemical conditions.</p> Graphical Abstract <p></p>
