Synthesis and Characterization of Molecular Composite Prepared from Layered Perovskite Oxide, HLa2Ti2NbO10
Young-Sik Hong, Si-Joong Kim
A layered perovskite oxide, RbLa2Ti2NbO10, was prepared and investigated for proton exchange and intercalation behaviors. Its protonated form, HLa2Ti2NbO10, exhibits the Brønsted acidity and reacts with organic amines. Polyoxonuclear cation, Al13, was then introduced into the interlayer by refluxing octylamine-intercalated compound with an Al13 pillaring solution. These layered oxides were characterized by X-ray diffractometer, thermogravimeter, Fr-infrared spectrometer and elemental analyzer. It is observed that the polyoxonuclear cation-pillared material exhibits a bilayer structure and is thermally more stable than organic counterpart at higher temperatures. The surface area of the pillared material annealed at 400 ℃ was the value of 25.1 m2/g.
