Abstract
In response to the pressing global climate crisis, the quest for sustainable energy alternatives has intensified, with hydrogen emerging as a leading contender due to its clean and renewable nature. This study explores the enhancement of hydrogen storage capacity using novel nanoelectrodes, specifically Cu-Fe-MWCNT and Cu-Co-MWCNT, as negative electrodes. The synthesis of these nanoelectrodes was achieved through an electrodeposition process, and their structural and compositional properties were examined using X-ray diffraction (XRD), Energy-dispersive X-ray spectrum (EDX), and scanning electron microscopy (SEM). The hydrogen storage capabilities of these materials were assessed via chronopotentiometry. The findings reveal that the Fe/MWCNT nanocomposite electrode offers improved stability and efficiency in hydrogen storage compared to the Co/MWCNT electrode, suggesting its potential as a superior material for electrochemical hydrogen storage applications. This research contributes to the advancement of hydrogen storage technologies and supports the role of hydrogen in the sustainable energy ecosystem.
