Abstract
Na-montmorillonite has been modified by ion exchange of simple Fe3+ or Keggin-type cations obtained via the partial hydrolysis of AlCl3 or t he co-hydrolysis of AICl(3)+FeCl2 mixture, in order to prepare catalys ts for NO decomposition. Temperature-programmed reduction, the most im portant characterizing method in this work, revealed that isomorphous substitution of iron for aluminium was not feasible, instead, co-hydro lysis and co-pillaring occurred, resulting in Fe,AI mixed pillared cla ys.
