Sumario:Layered perovskite oxides have attracted considerable attention due to their potential application in photoelectricity and catalysis. The unique character of layered perovskites as ion-exchange materials provides the possibility of creating structural diversity. A new ion-exchange reaction in aqueous solution was observed in layered oxide gamma-Bi(4)V(2)O(11). When employed in ion exchange, gamma-Bi(4)V(2)O(11) is converted into the scheelite-type phase (ABO(4)) by selectively discarding Aurivillius-type sheets, and is also converted into the A2X3 phase by selectively dissolving perovskite-like layers. Metal-doped BiVO(4) and Bi(2)O(3) were obtained using such an ion-exchange reaction.
