Formation of TiO2(B) by proton exchange and thermolysis of several layered alkali metal titanate structures
Titanates of the formula A2TinO2n+1 (3≤n≤5) consist of corrugated sheets of corner-sharing and edge-sharing TiO6 octahedra with monovalent cations occupying the interlayer spaces. The materials undergo rapid ion-exchange under relatively mild conditions, and thermal treatment of acid-exchanged materials has been shown to lead to the formation of new metastable forms of titanium dioxide (1).
