This study presents the design and application of two Fe(II)-based hybrid catalysts, [SiO₂@benzNP-FeII] and [SiO₂@benzNHP-FeII], for efficient hydrogen (H₂) production via formic acid (HCOOH) and formaldehyde (HCHO) dehydrogenation. The reduction of Schiff base ligands to incorporate N−H groups significantly enhances efficiency, stability, and reusability. Achieving >80,000 total turnover numbers (TONs), the results highlight their potential for sustainable energy solutions.
