Concurrent 2. Presentation for: Naturally derived carbon material for hydrogen storage

Abstract

Presented on Tuesday 17 May: Session 2

Over the last few decades, hydrogen storage has become a vital issue for hydrogen technologies. Several techniques, such as adsorbents, hydrides, nanomaterials, metal–organic frameworks and porous polymers, have been widely explored for hydrogen storage. Although some techniques are promising, there are still challenges, such as operating temperature and pressure, cyclic reversibility and higher hydrogen content. The concept of carbon-based nanomaterials in hydrogen storage, among all the systems that are up-and-coming, appears to be promising, especially the carbon nanotubes (CNTs), activated carbons, and carbon particle systems. This work reports on the development of carbon material from naturally available biomass, such as waste date leafs, through the pyrolysis method and its hydrogen capacity and comparison with commercial CNTs. The synthesised carbon nanomaterial was characterised using field emission scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, Raman spectroscopy, and the Brunauer–Emmett–Teller method. The date leaf carbon nanomaterial was found to have better surface area and pore‐size distribution than CNTs, which is promising for hydrogen storage.
