Promoting effect of NiAl2O4 for supported Ni particles on sprayed Ni/Al2O3 catalysts
Ni/Al2O3 catalysts were prepared by the spray reaction method. The NiO particles supported on NiAl2O4 were stabilized against the aggregation and converted into smaller Ni particles by H-2 reduction. The Ni particles stabilized on NiAl2O4 marked anomalous high activity for CO hydrogenation, due to the stronger interaction between Ni and NiAl2O4.
