A n-Hexyl NH3 Sr2 Nb3 O10 is obtained by the stepwise ion-exchange reaction, then is dispersed interlayer potassium cations of the perovskite niobate are exchanged with the partially hydrolyzed trinuclear acetato complex ions. On heating , the exchanged complex ions are converted into iron oxide pillars which keep the perovskite sheets apart. The product is characterized by XRD , SEM , EDAX and surface area measurement respectively.
