dc.description.abstractThis study introduces the novel Al2O3-supported nanobimetallic Co-La-B (Al2O3@Co-La-B) catalyst, specifically designed to enhance hydrogen production via sodium borohydride hydrolysis, marking its first application in hydrogen generation. 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.
