💡 Novelty & Significance:
Rare-earth Pr single-atom nano-stabilizers stabilize Fe-N4O sites by anchoring axial O, downshifting Fe d-band center and easing *OH desorption. FePr-ISAS/CN achieves 0.921 V half-wave potential, surpassing Fe-ISAS/CN and Pt/C, and 360 mW cm⁻² in Al-air batteries. This demonstrates rare-earth nano-stabilizer engineering as a novel route to durable, highly active oxygen reduction electrocatalysts.
