Historically, noble metals, particularly platinum (Pt) and its alloys, have set the benchmark for ORR catalysis due to their exceptional activity and selectivity . However, their limitations, including exorbitant costs, scarcity, and susceptibility to poisoning by reaction intermediates, have catalyzed the search for earth-abundant alternatives . Transition metal complexes, particularly Ni (II) and Co (II) Schiff base complexes, have emerged as promising candidates for non-precious metal catalysts. These complexes exhibit remarkable catalytic activity attributed to their distinctive electronic configurations, facile redox cycling, and capability to stabilize oxygen intermediates. Their relatively low synthesis cost, combined with their tunable electronic and steric properties, positions them as viable alternatives to noble metals for sustainable ORR catalysis. Despite these advancements, significant challenges persist in enhancing catalytic turnover frequency and operational stability under real-world conditions. The intrinsic sluggish kinetics of ORR demands the design of catalysts with optimized active sites capable of reducing activation energy and facilitating efficient oxygen adsorption, activation, and bond dissociation . Furthermore, many catalysts experience performance degradation due to insufficient electrochemical and structural stability in harsh operational environments. Addressing these challenges necessitates innovative approaches in catalyst design, leveraging the unique structural flexibility and electronic adaptability of Schiff base-metal frameworks.
