The rare-earth (La³⁺, Gd³⁺, or Er³⁺)-doped NiCo₂O₄ catalysts were supported on nickel foam to optimize charge rearrangement and structural reconstruction, thereby improving oxygen evolution reaction (OER) performance. Notably, the incorporation of La³⁺ collectively modulates the electronic configuration of Ni²⁺ and Co³⁺ through lattice distortion. It strengthens metal-oxygen bonding, thereby constructing the La—O—Ni/Co structural unit, which promotes charge transfer during the OER process and enhances catalytic activity. As a result, the ultrafine seagrass-shaped La-NiCo₂O₄-1 exhibited excellent OER activity. In a 1 mol·L^-1 KOH electrolyte, the prepared 0.25 mmol La³⁺ doped NiCo₂O₄ exhibited high OER activity with a low overpotential of 283 mV at 10 mA·cm^-2, along with outstanding stability for over 75 h at the multi-step chronoamperometry curve of 50→100→150→100→50 mA·cm^-2.
