Montmorillonites intercalated with Ce-Al pillars were synthesized. It was f
ound that the precursor of cerium and aluminum determined the presence of C
e-Al mixed oxide pillars. The catalytic performance in the 2-propanol conve
rsion of the various samples is discussed in terms of the catalyst structur
e. It was found that the surface features of these interlayered materials a
re different from those of large ceria-alumina particles.
