AbstractThe hydrogen adsorption capacity of various carbon nanostructures including single-wall carbon nanotubes, graphitic nanofibers, activated carbon, and graphite has been measured as a function of pressure and temperature. Our results show that at room temperature and a pressure of 80 bar the hydrogen storage capacity is less than 1 wt.% for all samples. Upon cooling, the capacity of hydrogen adsorption increases with decreasing temperature and the highest value was observed to be 2.9 wt. % at 50 bar and 77 K. The correlation between hydrogen storage capacity and specific surface area is discussed.

The hydrogen adsorption on platinum (Pt)-decorated carbon nanocenes (CNCs) are investigated by DFT calculations. The Pt is an active site for hydrogen adsorption while curvature of CNC enhances hydrogen uptake via hydrogen migration/diffusion on the C–C surface.

carbon nanotubes were synthesized by pyroysis method using copper nanoparticles as catalyst. The structure, phase composition and hydrogen storage capacity were investigated by TEM, XRD spectra and Electrochemical System. The results show that the diameter of carbon nanotubes is 200-500nm, The P-C-T curve of adsorbing hydrogen of samples was measured in the pressure up to 12 MPa at room temperature. we show that a SWNT can strongly adsorb up to 8-wt% hydrogen. These results advance our fundamental understanding of dissociative adsorption of hydrogen in nanostructures and suggest new routes to better storage and catalyst materials.

ABSTRACTA Sieverts apparatus for small quantity samples has been implemented by employing a very small volume pressure reservoir and a sample chamber of less than 1 ml. The hydrogen storage capacity of a commercially available, HiPco (high pressure CO conversion) single-wall carbon nanotube (SWNT) was measured over a hydrogen pressure range of 0-35 Bar at room temperature. The sample contained approximately 5 wt% of residual Fe catalyst, and showed 0.17 wt% of hydrogen uptake capacity at 30 Bar of hydrogen pressure. Palladium nanoparticles were deposited on the SWNT via electrochemical method (EC) from H2PdCl4 solution. The storage capacity of the SWNT with EC-doped Pd was increased to 0.52 wt% at 30 Bar, which corresponds to the capacity enhancement by a factor between 2.8 and 3.1.
