Highly thermostable, porous, layered titanoniobate pillared by silica

Abstract
The first silica-pillared titanoniobate has been prepared by firstly intercalating layered titanoniobate with NH2(CH2)3Si(OEt)3 and subsequently thermally removing the interlayered organics, the resulting pillared material is porous and has a high thermal stability beyond 750 °C.
