Zirconia-Pillaring in Layered HNb O and HNbMoO.

In this work, the pillaring of two layered niobium-based oxides (HNb O and HNbMoO ) with zirconia was investigated in detail. Two novel zirconia-pillared layered metal oxides, zirconia-pillared layered HNb O and zirconia-pillared layered HNbMoO , have been successfully prepared. Both pillared products exhibited a higher thermal stability exceeding 673 K.
