The Schiff base ligand, with its versatile azomethine group, tunable steric properties, and strong chelating capabilities, emerges as an ideal scaffold for designing advanced catalysts. Its ability to stabilize transition metal centers while allowing for electronic delocalization and redox activity provides a robust platform for enhancing catalytic performance. Such structural and electronic versatility positions Schiff base ligands as key components in the development of sustainable and efficient catalysts for critical reactions like ORR. The promise shown by the Ni (II) Schiff base complex underscores the importance of further research in this domain. A deeper exploration of Schiff base ligands, including functionalized derivatives and their coordination to various metal centers, could unlock new pathways for advancing clean energy solutions and addressing global energy challenges.
