Abstract

Na-montmorillonite has been modified by ion exchange of simple Fe3+ or Keggin-type cations obtained via the partial hydrolysis of AlCl3 or the co-hydrolysis of AlCl3+FeCl2 mixture, in order to prepare catalysts for NO decomposition. Temperature-programmed reduction, the most important characterizing method in this work, revealed that isomorphous substitution of iron for aluminium was not feasible, instead, co-hydrolysis and co-pillaring occurred, resulting in Fe,Al mixed pillared clays.
