Schiff bases have emerged as promising catalysts for hydrogen evolution reactions (HER), offering a novel approach to green energy production . The unique structural features of Schiff bases, including the C=N bond and the ability to form stable complexes with metal ions, make them particularly suitable for catalytic applications . A recent study proposes a novel Schiff base catalyst, N, N'-bis(2-hydroxy-1-naphthaldehyde)-o-phenylenediamine ([naph]2-o-ph), for hydrogen production, demonstrating high capability in generating hydrogen through a mechanism involving protonation and electron exchange on the Schiff base .
