Structural Evolution of Manganese Oxides via Surfactant-Free Solvothermal Routes

Abstract:

The preparation of γ-MnOOH nanorod and Mn₃O₄ nanooctahedra have been achieved via hydrothermal reaction between KMnO₄ and DMF in water without the use of any surfactant or template. Various measurements were used to characterize the structure, morphology and electrochemical behavior of the resultant products. A possible growth mechanism has been proposed, the reaction temperature and the concentration of DMF plays a crucial role in the formation of the products. Their electrochemical properties have also been discussed.
