There is disclosed a multi-metal-nitrogen compound for use in hydrogen storage materials. The compound comprising two dissimilar metal atoms and a nitrogen atom. The multi-metal-nitrogen compound being capable of absorbing hydrogen at an absorption temperature and pressure, and of desorbing 60% or more by weight of said absorbed hydrogen at a desorption temperature and pressure.

Multi-metal-nitrogen compounds for use in hydrogen storage materials

This invention relates to a method of producing multi-walled carbon nanotubes (MWNT) by catalytic decomposition of gaseous carbon-containing compounds over a transition metal-based catalyst. The catalyst comprises A-B and a support, wherein A is selected from the group VIII transition metal elements and B is selected from the Group VIB transition metal elements. An additional aspect of this invention includes a method of preparing hydrogen gas.

Carbon nanotubes fabrication and hydrogen production

Metal-N-based or metalloid-N-based materials absorb a substantial amount hydrogen and are useful as hydrogen storage materials for various applications such as hydrogen fuel cell technology.
