Abstract:

A new material, Zn-containing derivative from SrBi2Nb2O9, was synthesized by multi-step ion-exchanges with H+/(BiO)+, TMA+ (tetramethylammonium ions)/H+, and Zn(NH3)42+/TMA+ step by step. X-ray diffraction (XRD) patterns exhibite the difference in the layered structures among the precursor SrBi2Nb2O9 (SBN), its protonated product (HSN), and Zn-containing derivative (ZSN). The compositional analyses reveal the extraction of most of the bismuth atoms and the loss of a small part of the strontium atoms after protonation. The UV-Vis (ultraviolet-visible) absorption edge of the Zn-containing derivative shifts markedly to high energy compared with that of the precursor and its protonated product.

Key words: SrBi2Nb2O9, protonation, ion-exchange, UV-Vis absorption
