摘要：
A n-Hexyl NH 3Sr 2Nb 3O 10 is obtained by the stepwise ion-exchange reaction,then is dispersed in aqueous solution of trinuclear acetato-hydroxo iron(III) nitrate,[Fe 3(OCOCH 3) 7OH·2H 2O]NO 3,and the 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.
