Carbon nanotube hydrogen energy storage

Can carbon nanotubes be used in hydrogen production and storage?

Carbon nanotubes have garnered significant interest due to their promising applications and facile synthesis. This study highlights the applications of CNTs in the field of hydrogen production and storage.

Can carbon nanotubes adsorb hydrogen?

Four methods are available for hydrogen storage: liquefaction, compression, storage under chemical bonds, and storage under physical bonds. Carbon nanotubes (CNTs) have been considered, since the end of the 1990s, as interesting materials to adsorb hydrogen, but over time many criticalities have emerged.

Are lithium-doped carbon nanotubes a promising hydrogen storage media?

We investigated Li-doped carbon nanotubes (CNTs) as a promising hydrogen storage media. In this computational model, we considered isolated lithium atom adsorbed on a CNT wall as an adsorption site...

What are carbon nanotubes (CNTs)?

Can hydrogen gas molecules be stored in a carbon-based nanomaterial?

Hydrogen storage is an active area of research particularly due to urgent requirements for green energy technologies. In this paper, we study the storage of hydrogen gas molecules in terms of physical adsorption on a carbon-based nanomaterial, i.e., a novel graphene-carbon nanotube hybrid.

Can a nanotube improve hydrogen storage capacity?

Theoretical studies have suggested that the curvature of the nanotube surface can enhance the binding energy of hydrogen compared to flat graphene sheets, potentially leading to improved storage capacities. Experimental investigations have provided valuable insights into the hydrogen storage capabilities of CNTs.
