Characterized by X-ray diffraction, Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, Brunauer-Emmett-Teller analysis, and scanning electron microscopy, the catalyst exhibits a porous, homogeneous cubic structure which significantly contributes to its high catalytic efficiency. It demonstrated remarkable hydrogen generation rates of up to 6057.72 mL(H2) min(-1) g(cat)(-1) at 30 degrees C and maintained 91.63% catalytic activity over multiple cycles, with a notable increase to 8661.94 mL(H2) min(-1) g(cat)(-1) at 60 degrees C. Kinetic studies, utilizing nth-order and Langmuir-Hinshelwood models, indicated activation energies of 51.38 kJ mol(-1) and 49.33 kJ mol(-1), respectively, showcasing the catalyst's potential as a sustainable solution for hydrogen production in various industrial applications.eninfo:eu-repo/semantics/openAccessH-2 generationCatalytic activityNaBH4 hydrolysisAl2O3@Co-La-B catalystKineticsArticleN/AWOS:001221512500001Q22-s2.0-8519283029110.1007/s41779-024-01035-5
