Abstract Various nickel catalysts deposited on classical supports (Si0 2 , A1 2 0 3 , MgO) and on less conventional materials (TiO 2 , ThO 2 , CeO 2 , ZrO 2 , Cr 2 0 3 ) were prepared under conditions in which the strong metal support interaction of the Pt/TiO 2 -type does not occur. Their catalytic properties for ethane hydrogenolysis and carbon monoxide hydrogenation and the reducibility of the nickel phase deduced from magnetic measurements were investigated. Activity toward ethane hydrogenolysis per unit area varies by two orders of magnitude when the nature of the support is changed. A correlation between activity and nickel reducibility is demonstrated and interpreted in terms of geometric effects of dilution due to the presenceof unreduced surface-nickel species. These dilution effects are shown to play an important role in the case of the CO + H 2 reaction. However, additional effects leading to changes in apparent activation energy (not yet well understood but possibly linked to the carbon monoxide coverage) result in a poorer correlation between activity, selectivity toward C 2+ and nickel reducibility. These correlations lead to an interest in designing further experiments to study what can be termed the redox metal support interaction, which should not be confused with the strong metal support interaction.

Abstract The textural stabilization of non-porous zirconia has been obtained by addition of lanthanum or yttrium oxides. The improved stability of the promoted zirconia has been traced to the structural stabilization of the tetragonal form of ZrO2.
