Abstract
Abstract: In this study, carbon nanomaterials (CNMs) were synthesized from waste cotton fibers and examined their hydrogen adsorption capacity. The CNMs were created by subjecting waste cotton fibers to high-temperature pyrolysis at 800°C, followed by activation with alkali solution. Nano-sized metallic particles of Nickel and Aluminium were decorated on the activated carbon fibers. Analysis through SEM, EDAX, Raman spectroscopy, X-ray diffraction and BET surface area confirmed the porous nature and presence of metal particles in the CNMs. These materials exhibited a notably larger specific surface area (SSA) compared to untreated carbon fibers, enhancing their hydrogen storage capabilities as it showed 8.08 wt% of hydrogen adsorption using a Sievert's apparatus. This work, shows the promising potential of these CNMs for hydrogen adsorption in various industrial applications.
