The necessity for non-platinum catalysts in the context of hydrogen evolution is predominantly driven by the limited availability and substantial cost of platinum, which is currently the most effective catalyst for this reaction . This cost-effectiveness issue renders large-scale hydrogen production economically unfeasible. Schiff base ( i R-C=N-R ii ) ligands have emerged as compelling alternatives due to their affordability, accessibility as precursors, adaptability to desired properties, and ease of synthesis. A Schiff base ligand is a compound characterized by a double bond between a carbon and nitrogen atom . This bond is formed through the condensation reaction of an aldehyde or ketone with a carbonyl group with a nitrogen-based compound. The capacity to promptly establish coordination with transition metals is paramount for the effective facilitation of proton reduction, a process that culminates in the generation of hydrogen gas .
