Increasing the hydrogen storage capacity of single-walled carbon nanotube (SWNT) through facile impregnation by TiO2, ZrO2 and ZnO nanocatalysts
Various nanocomposites of TiO2, ZnO and ZrO2 decorated single wall Carbon nanotubes (SWNTs) were fabricated by facile and template free continuous ultrasonication/stirring of virgin metal oxide nanopowders and SWNTs in ethanol under UV-light illumination. The TEM micrographs showed that nanoparticles (NPs) were uniformly dispersed and bonded on the surface of SWNTs. The results of XRD as well a...
متن کاملStudy the stability of Si, Ge, Fe and Co in the interior surface of metallic carbon nanotube for hydrogen storage
In this article, we have performed calculations for studying the stability of the carbon group elements such as Si and Ge and also the magnetic elements like Fe and Co via first principle investigations. We found that Si and Ge decoupled from the interior surface of carbon nanotubes, this fact was independent in curvature, radius, conductivity and numbers of atoms in the carbon nanotubes. But t...
متن کاملHydrogen Storage Capacity of Carbon-Foams: Grand CanonicalMonte Carlo Simulations
Hydrogen storage in the three-dimensional carbon foams is analyzed using classical grand canonical Monte Carlo simulations. The calculated storage capacities of the foams meet the material-based DOE targets and are comparable to the capacities of a bundle of wellseparated similar diameter open nanotubes. The pore sizes in the foams are optimized for the best hydrogen uptake. The capacity depend...
متن کاملTheoretical evaluation of hydrogen storage capacity in pure carbon nanostructures
Carbon nanotubes have been proposed as promising hydrogen storage materials for the automotive industry. By theoretical analyses and total-energy density functional theory calculations, we show that contribution from physisorption in nanotubes, though significant at liquid nitrogen temperature, should be negligible at room temperature; contribution from chemisorption has a theoretical upper lim...
متن کاملIrradiation-induced stiffening of carbon nanotube bundles
Recent experiments have demonstrated that electron irradiation of bundles of single-walled carbon nanotubes resulted in dramatic increase of the bundle bending modulus at moderate irradiation doses, followed by a decrease in mechanical properties at higher doses. To understand such a behavior, we employ molecular dynamics simulations with empirical potentials and analytical approximations to ca...
