Synthesis,Characterization and Electrochemical Performance of Polyoxometalates(β-SiW9)-Pillared Layered Double Hydroxide
Abstract：In this paper,we prepared a novel polyoxometalates-intercalated hydrotalcite inorganic com-posite functional material,using Mg-Al Layered Double Hydroxide (LDH)and theβ-Na9HSiW9O34 21H2O (referred to as theβ-SiW9 )as precursors,through the LDH interlamellar anion exchangeability.The struc-ture,morphology and properties of the products were characterized by X-ray diffraction (XRD),infrared spectroscopy(FT-IR),TG-DTA(TG-DTA),scanning electron microscopy(SEM)and electrochemical cyclic voltammetry (CV).The results showed thatβ-SiW9 was successfully inserted into the LDH layers,repla-cing the original nitrate ions,and a new type ofβ-SiW9-LDHs composite was synthetized.
