The 10th Global Conference on Polymer and Composite Materials (PCM 2023)

Abstract: Hydrogen is a clean fuel and environmentally friendly source of energy. It can be utilized in diverse applications, including vehicles, aircraft, portable power to transportation, etc. Therefore, progressive research and development in area of hydrogen storage is ongoing. Nanotubes, having large surface to volume ratio, are attractive materials for hydrogen storage. Besides carbon nanotubes, other non-metallic nanotubes such as silicon carbide nanotube (SiCNTs) have been predicted as potential nanomaterials for hydrogen storage. In this talk, I shall focus on hydrogen adsorption properties of sulphur-doped (S-doped) SiCNTs using first-principles calculations based on density functional theory. The calculated energy band structures, density of states, charge transfer and adsorption energy will be discussed. At the end, the talk would be concluded with future prospects of work in this area.
