Hydrogen storage in different carbon nanostructures

Abstract

Carbon nanostructures of different kinds have been synthesized by chemical vapor deposition. By modifying the deposition temperature, the catalyst material, and the hydrocarbon, nanofibers with herringbone structure, multi-walled nanotubes with tubular structure, and single-walled nanotubes were deposited. The nanostructures were purified with different treatment methods. The carbon nanostructures were characterized using scanning and transmission electron microscopy. The hydrogen storage capability was investigated for all obtained nanostructures. The measurements show that the storage capacity of hydrogen is very limited in all the carbon nanostructures.
