INFLUENCE OF SYNTHESIS CONDITIONS ON THE MORPHOLOGY OF NEW COBALT MANGANESE DIOXIDES

摘要

The morphology of new cobalt doped 7-MnO2 synthesized by the electrochemical-hydrothermaI route is described. Various surface morphologies wereobserved for these samples depending on the synthesis conditions. The effects of the presence of Co2+ ions in the initial solution, the synthesis temperature, the pH and the applied current density on the morphology obtained are discussed.
