Clay-Based Nanocomposites as Eco-friendly Materials for Electrochemical Hydrogen Storage

چکیده مقاله

Clay is an important natural substance. With a better understanding of clay structure, montmorillonite may be used in more components and products for catalysis, food addi-tives, antibacterial action, polymers, sorbents, etc. Clay-based materials are promising for energy conversion and storage1, 2. Recent years have seen hydrogen energy consumption increase. Clean, safe, and adapta-ble hydrogen helps decarbonize transport. Renewable energy development improves energy efficiency and decarbonizes the system. Hydrogen's non-toxicity, quantity, and ease of prep-aration make it an intriguing fuel3, 4. This study presents the innovative implementation of clay-based nanocomposites for the purpose of hydrogen storage. The Li-Co-Mn double spinel was synthesized using the com-bustion technique using carboxylic acid as both the fuel and chelating agent. This double spinel compound was employed as the electrocatalyst in this study. The produced samples were analyzed using different methods including XRD, EDS, and SEM to determine their purity and morphology. This study investigates the hydrogen storage capacity of nanocom-posites manufactured using chronopotentiometry charge-discharge procedures. The results suggest that the incorporation of Li-Co-Mn spinel oxide nanoparticles into the clay layers leads to an increase in discharge capacity, representing a greater capacitance compared to pure clay. The findings of our study suggest that the use of Li-Co-Mn spinel oxide nanopar-ticles for modification has potential as an economical approach to enhance the electrochem-ical performance of clay-based materials.
