Green hydrogen (H2) offers a sustainable alternative to non-renewable energy sources. This study focuses on enhancing H2 generation from sodium borohydride (NaBH4) using platinum nanoparticle (Pt-NP) catalyst supported niobium-based coordination compound, [Nb(BDC)0.9(PDC)0.1]n, synthesized via solvothermal method with 1,4-benzenedicarboxylic acid (BDC) and 2,5-pyridinedicarboxylic (PDC). Characterization techniques including Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), Brunauer–Emmett–Teller (BET) analysis, Raman spectroscopy, diffraction (XRD) confirm the morphology, composition, surface area (398.583 m2g−1), crystallinity of material. The in situ Pt-NPs showed rate (HGR) 86.588 mL min−1 g−1 when alone, while achieved an enhanced HGR 119.020 under optimal conditions (10 mmol% Pt, 0.5 mmol NaBH4, 303.15 K). low activation (Ea) 16.38 kJ mol−1 indicates efficient catalysis. maintained stable performance recycling tests, demonstrating its potential for practical applications evolution NaBH4.
