The reasonable design and modulation of the electronic properties Pd metallene are acknowledged as a promising avenue for enhancing oxygen reduction reaction (ORR) in anion exchange membrane fuel cells (AEMFCs), yet they remain formidable challenge. Herein, thin-sheet structure Zr-doped (PdZr metallene) with abundant defects is proposed using facile wet-chemical approach efficient highly durable ORR electrocatalysis. Multiple microstructural analyses uncover that orchestrated oxophilic regulation PdZr via Lewis-acidic Zr site could concurrently optimize configuration Pd, downshift d-band center and, thus, promote intrinsic activity. Benefiting from unique two-dimensional morphology optimization facilitated by coupling effect, resultant demonstrates significantly enhanced electrocatalytic performance basic solutions, high half-wave potential (
