摘要

Based on the Keggin-type silicotungstic acid and thiourea, a new inorganic-organic hybrid with lamellar shape has been synthesized by a mechanochemical route at room temperature. The heteropolyanions still retained the Keggin-type structure in the hybrid. It was designed as a carbon paste electrode to investigate its electrochemical properties. The sample shows the characteristic electrochemical properties of Keggin-type polyanions, holding three couples of stable and reversible redox peaks in the range of-0.15 similar to-0.73 V, which may arise from the maintenance of Keggin-type polyanions and the pore structure of lamina. This work proposed a new synthetic route for polyoxometalates-based hybrid, and offered an effective method to investigate the property of polyoxometalate-based hybrid under the solid state condition.
