Electrochemical and Chemical Syntheses of the Hybrid Organic−Inorganic Electroactive Material Formed by Phosphomolybdate and Polyaniline. Application as Cation-Insertion Electrodes

We report a hybrid organic−inorganic electroactive material composed of a conducting polyaniline matrix and the phosphomolybdate anion ([PMo12O40]3-) as the active inorganic component. The material can be prepared electrochemically as thin films or chemically in the bulk, in the absence of other com...

Description
Summary:We report a hybrid organic−inorganic electroactive material composed of a conducting polyaniline matrix and the phosphomolybdate anion ([PMo12O40]3-) as the active inorganic component. The material can be prepared electrochemically as thin films or chemically in the bulk, in the absence of other competing anions. The phosphomolybdate anion is anchored within the polymer matrix and not exchanged upon reduction. The material presents good conductivity and electroactivity, and it represents an example of electrodes that can take advantage of the electroactivity of zero-dimensional molecular species. A preliminary analysis of the material as a cathode in reversible lithium batteries is discussed.
