Active and selective Ni-based catalysts for the production of hydrogen thro
ugh the decomposition of methane were looked for. The most active catalyst
having the longest life time was a nickel catalyst supported on Cab-O-Sil.
Approximately 1200 carbon atoms per a nickel atom deposited on the Ni(5 wt%
)Cab-O-Sil catalyst at 793 K before a complete deactivation was observed.
