Precise construction of symmetrically coordinated triatomic zirconium catalyst for efficient oxygen reduction

coordination configuration shifts the d-band center of zirconium toward the Fermi level, effectively adjusting the adsorption energy of the oxygen intermediate by elongating the O-O bond through bridge adsorption, thereby effectively promoting the breaking of the bond. This study reveals the synergistic effect of triatomic zirconium active centers for improving the ORR performance.
