Abstract

Mesostructured niobium oxide was prepared by ion exchange reaction using layerd perovskite K₂NbO₃F and C12, C16, C18-alkyltrimethylammonium(CnTMA) surfactants. Lamellar-type niobium oxide-CnTMA complexs were synthesized at 70°C in high pH (10-11) solution for n=16 and 18 and they transformed to 2d-hexagonal-type complex by the treatment in low pH (4-5) HCl solution. For n=12, hexagonal-type complex was synthesized even at high pH condition.
