The results unequivocally establish the Ni (II) Schiff base complex as an ideal catalyst for the ORR, demonstrating superior catalytic efficiency, faster reaction kinetics, and a lower overpotential compared to its Co (II) counterpart. The optimized interaction between the Ni (II) center and the Schiff base ligand contributes to the complex's enhanced stability, efficient electron transfer, and precise intermediate stabilization, critical factors for achieving high-performance ORR catalysis. The ability of the Schiff base ligand to modulate the electronic structure of the Ni (II) center further enables the reduction of energy barriers and facilitates the rate-determining steps, making it a prime candidate for next-generation energy conversion and storage technologies.
