In previous research, Fe-M (M=Pd, Mo, Ni) bimetallic catalysts on gamma-alumina supports were developed by our group that exhibited high activity for catalytic methane decomposition into pure hydrogen and multi-walled carbon nanotubes (CNT). In the current work, a basic Mg(Al)O support was prepared by calcination of Mg-Al hydrotalcite. Nanoparticle inclusion techniques were used to prepare monosized (12 nm) Fe-Ni nanoparticles, which were dispersed on the Mg(Al)O. These catalysts exhibited high activities and good lifetimes for the production of pure hydrogen and CNT from methane. Additionally, the CNT were easily cleaned by a one-step treatment in dilute nitric acid.
