Optimum conditions for intercalation of lacunary tungstophosphate(V) anions into layered Ni(II)–Zn(II) hydroxyacetate

摘要

Acetate containing nickel–zinc hydroxysalts (LHS-Ni–Zn) have been synthesized by coprecipitation and hydrothermal treatment. The acetate anions were exchanged with PW12O403? anions, and optimum conditions to attain the maximum level of W in the compound have been identified. The W intercalated compound was characterized by powder X-ray diffraction, FT-IR spectroscopy, thermogravimetric and differential thermal analyses, scanning electron microscopy and transmission electron microscopy.
