Hydrogen storage in graphite nanofibers

Article Abstract:

Graphite nanofibers that have ostensibly been discharged of hydrogen were investigated using temperature-programmed desorption. Results suggested that a significant fraction of hydrogen is sorbed and retained in the nanofibers when exposed to gas pressures of 120 atm at 25 degrees Centigrade. The need for high temperatures for complete desorption indicates that a strong interaction with both graphite walls and other neighboring molecules is established once the hydrogen molecules are confined within the pores.

Graphite nanofibers as an electrode for fuel cell applications

Article Abstract:

The physiochemical effects of GNF-supported platinum particles on the electrocatalytic oxidation of menthol, when compared with a traditional support medium, Vulcan carbon are explored. Changes in the catalytic mechanism indicate that significant mechanistic changes occur when the carbon support material is tailored in terms of composition, crystallinity, and morphology.

Immobilization of hydroquinone through a spacer to polymer grafted on carbon black for a high-surface-area biofuel cell electrode

Article Abstract:

A high-surface-area biofuel cell electrode formed by immobilization of hydroquinone through a spacer to polymer grafted on carbon black is described. The potential at which an anodic current began to increase was more negative by about 0.2 V than that for a vinylferrocene-mediated electrode while the increase in the anodic current density was of the same order.
