Abstract The isomerization ofn-butene was used as a model reaction on a series of aluminas in order to find relationships between their catalytic activity and their structural and textural characteristics. The results show that the nature of the precursor, either gibbsite or boehmite, from which the alumina is obtained plays an important role in the catalytic activity. If the same precursor is considered the presence of pentacoordinated aluminum on the surface generates sites which influences deeply the product selectivity. Thus, besides structural aspects, detectable by MAS NMR, and textural factors such as surface area and pore size distribution, there are more subtle effects linked to the nature of the precursor which are not explained so far.
