Abstract
In this paper, the hydrogen generation from the hydrolysis of NaBH4 with plasma treated Co-B-P catalyst are investigated as based on NaBH4 concentration, NaOH concentration, temperature, plasma applying time and plasma gases. The changes in surface chemistry and morphology induced by the plasma treatment are examined using scanning electron microscopy (SEM), N2 adsorption-desorption, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The hydrogen generation rate from hydrolysis of NaBH4 with Co-B-P prepared in the presence of plasma is completed in 12Â min time intervals that exhibited a higher hydrogen generation rate of 60%, while the Co-B-P produced in known method let to slower hydrogen release, and the hydrolysis is completed in 30Â min time intervals. The maximum hydrogen generation rates of the plasma treated and plasma untreated Co-B-P catalysts toward NaBH4 hydrolysis are 3976 and 1807Â mL/g/min, respectively. The activation energy for zero-order is found to be 49.11Â kJÂ molâ1.
