Hydrogen storage in multilayer carbon nanotubes

Abstract

Multilayer carbon nanotubes obtained by pyrolysis and mechanical activation of plant derived amorphous carbon are excellent sorbents for hydrogen.

State-of-the-art on the production and application of carbon nanomaterials from biomass

“…It seems to that high pressure was essential to promote the diffusion of the targeted gas into the inner structure of conventional CNMs for most of the adsorption/storage processes 178 . However, Onishchenko et al reported that biomass-based CNTs derived from mechanical activation of rusty peat moss, katerina SV corn, priozernyi-4 cotton and thorny bamboo presented excellent H2 adsorption capability even at a low pressure (0.5 MPa) and at room temperature (24 ℃) [179][180][181] . It was found that the adsorption capacity of H2 were greatly affected by the type of feedstock, the mechanical activation time, the adsorption pressure and the adsorption temperature.…”

Thermal stability of multilayer carbon nanotubes produced by the mechanical activation of amorphous carbon

“…The properties of multilayer carbon nanotubes cre ated by the mechanical activation of amorphous car bon that, in turn, had been obtained from brown sph agnum moss, corn waste, cotton, and spiny bamboo were considered in [3][4][5][6][7][8]. Treatment in a planetary mill for 1-27 h was used for mechanical activation of the amorphous carbon.…”

“…The volume of the carbon nanotubes formed in the mechanical activation of amorphous carbon depends linearly on the time of mechanical activation (1-27 h) in the planetary mill [5].…”
