in alkaline media. This enhancement is ascribed to the electron-rich ferrocene moieties, which act as efficient electron-transfer mediators during catalysis. DFT calculations corroborate these findings, revealing a theoretical overpotential of 0.79 eV for the dual-ferrocene-substituted catalyst. These results underscore the critical role of ferrocene in lowering the overpotential of molecular OER catalysts.
