摘要：

Stepwise intercalations of n-decylamine and oligosiloxanes followed by calcination at 823 K in air results in a thermostable supergallery layered lanthanum niobate; the new material shows an interlayer free spacing of 17.4 Angstrom along with a high Brunauer-Emmett-Teller surface area of 251 m(2) g(-1); the acidity of the new pillared material is markedly enhanced with respect to the original lanthanum niobate.
