Abstract

Preparation and characterization of the titanate films intercalating various metal cations between the titanate layers from transparent titanate sol were investigated. UV irradiation to the titanate films containing chelate complexes could decompose the organic ligand to yield metal ion-intercalated titanate films. The chelation of metal ions would decrease the charge density of the metal ions to reduce the interaction between the titanate sheet and the metal cation, forming the stable sols.
