Abstract:<\/h4>\n
Novel nitrogen-doped carbon hybrid materials consisting of multiwalled nanotubes and porous graphitic layers have been produced by chemical vapor deposition over magnesium-oxide-supported metal catalysts. CN x nanotubes were grown on Co\/Mo, Ni\/Mo, or Fe\/Mo alloy nanoparticles, and MgO grains served as a template for the porous carbon. The simultaneous formation of morphologically different carbon structures was due to the slow activation of catalysts for the nanotube growth in a carbon-containing gas environment. An analysis of the obtained products by means of transmission electron microscopy, thermogravimetry and X-ray photoelectron spectroscopy methods revealed that the catalyst’s composition influences the nanotube\/porous carbon ratio and concentration of incorporated nitrogen. The hybrid materials were tested as electrodes in a 1M H 2 SO 4 electrolyte and the best performance was found for a nitrogen-enriched material produced using the Fe\/Mo catalyst. From the electrochemical impedance spectroscopy data, it was concluded that the nitrogen doping reduces the resistance at the carbon surface\/electrolyte interface and the nanotubes permeating the porous carbon provide fast charge transport in the cell.<\/p>\n","protected":false},"excerpt":{"rendered":"
