Abstract

Nanoscale layered tetratitanate K₂Ti₄O₉ powders were prepared at relatively low temperature by a stearic acid method. The structures of the titanates and the products which had undergone H⁺, Ag⁺ exchange and intercalated by propylamine and NH₂(CH₂)₃Si(OC₂H₅)₃ (APS) were investigated by XRD, TEM, TG and BET analysis. Compared with the larger-size products prepared by a conventional solid state reaction, the nanoscale K₂Ti₄O₉ takes in more intercalating molecules and leads to larger interlayer distances in the intercalated products, which may facilitate the exfoliation of the layered compound.
