摘要：

The preparation of TiO2-pillared mica was carried out in a CH3COOH aqueous solution. Titanium ion species were obtained by an addition of Ti(C3H7O4 to an aqueous solution of CH3COOH and by subsequent aging of the solution for a prescribed time followed by intercalation of these ionic species into the interlayers of mica. Ti4+-intercalated mica was thus obtained by ion exchange. After the sample was calcined at 773 K in air, TiO2-pillared mica was produced. The pillaring of TiO2 in the interlayer of mica was confirmed by XPS. The surface area TiO2-pillared mica was about 100 times larger than that of mica alone. The basal spacings of the products heated above 523 K were in the range from 2.01 nm to 2.68 nm in the samples obtained under various conditions.
