Screening of metal oxide catalysts for carbon nanotubes and hydrogen production via catalytic decomposition of methane (2006)
Presentation / Conference Contribution
Zein, S. H., Mohamed, A. R., & Chai, S. P. Screening of metal oxide catalysts for carbon nanotubes and hydrogen production via catalytic decomposition of methane

A number of catalysts prepared from transition metals such as copper (Cu), iron (Fe), nickel (Ni), cobalt (Co) and manganese (Mn) on TiO 2 support were tested for the decomposition of methane into hydrogen and carbon. These catalysts were used in the... Read More about Screening of metal oxide catalysts for carbon nanotubes and hydrogen production via catalytic decomposition of methane.
