Abstract
Ion-exchange of K1.19H0.81V2Mo3O15·nH2O with a layered type structure prepared from K2V2Mo3O15 via ion-exchange reaction is attempted with alkaline and alkaline earth ions. Both of potassium and proton in the interlayer space are partially ion-exchanged to yield (K, A, H) 2V2Mo3O15·nH2O (A; alkaline and alkaline earth metal). The uptake amount of Li+ ion is very small and no uptake amount of Mg2+ ion is observed, and the uptake amount of other ions increases with their ionic sizes. The basal spacings of hydrated phases for ion-exchanged compounds are independent of ionic size, but those of dehydrated one except the Li and Ca derivatives increase with ionic size.
