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.

Herein, the development of a niobium-based metal–organic framework (Nb-MOF) designed to serve as catalytic support for production hydrogen (H2) from sodium borohydride (NaBH4) is reported. The Nb-MOF was synthesized via solvothermal method using niobium ammoniacal oxalate (AmOxaNb) metal source and 1,4-benzenedicarboxylic acid (BDC) ligand. resulting MOF characterized by Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS). characterization study confirmed successful synthesis Nb-MOF. activity optimized examining five key factors: (i) platinum (Pt) cobalt (Co) bimetallic compositions (ranging 1:0 0:1 mmol), (ii) NaBH4 concentration (0.2, 0.3, 0.4, 0.5 mol L−1), (iii) Nb-MOF/Pt–Co catalyst dose (0.05, 0.10, 0.20, 0.40 (iv) hydroxide (NaOH) (0.01, 0.05, 0.1, 0.2 (v) system temperature (293.15, 298.15, 303.15, 313.15, 323.15 K). optimal identified supporting Pt-Co composition in 0.4:0.6 mmol ratio, achieving generation rate (HGR) 1473 mL min−1 gcat−1 an activation energy 19.2 kJ mol−1. Furthermore, this maintained its efficiency over 20 cycles, demonstrating significant potential sustainable solution H2 evolution NaBH4.
