Preparation, characterization and oxygen reduction catalytic activities of nanocomposites of Co(ii)/montmorillonite containing polypyrrole, polyaniline or poly(ethylenedioxythiophene)

Cobalt(ii)/conducting polymer/montmorillonite composites are synthesized through ion exchange of montmorillonite (MMT) followed by oxidative polymerization using Co(iii) as the oxidant. Composites are characterized and used as electrocatalysts.
