Synthesis and electrochemical properties of silver coordination polymer based on phosphotungstic heteropolyacid

Abstract:

In this work, a silver ion coordination polymer material ([Ag2(BPBP)3PW12O40]), based on phosphotungstic heteropolyacid (H3PW12O40) was synthsised by hydrothermal method. Single crystal X-ray diffraction analysis showed that silver ion was connected with organic ligands to form a one-dimensional chain, while Ag-O bonds linked POMs which located on one side of the chain. The chains form to final three-dimensional structure through supramolecular interactions such as hydrogen bonds. We used carbon electrode (GCE) as the working electrode, and investigated the electrochemical properties of the material. Meanwhile, we studied the thermal stability of the material.
