Self-assembled amorphous manganese oxide/hydroxide spheres via multi-phase electrochemical interactions in reverse micelle electrolytes and their capacitive behavior
Abstract
Amorphous matrices of three-dimensionally interconnected MnOx/MnOOH nano-spheres were electrochemically assembled onto a carbon substrate by a pulse galvanostatic method (PGM) in a nonionic reverse micelle electrolyte. The synthesized material showed a unique morphology which was attributed to a synergistic effect between the amphiphilic molecule based interface membrane as a soft template and the PGM approach. The transfer of the reactant was remarkably special because of the elusive thermodynamic and kinetic parameters of the interactions at the interface between the two different phases such as the polar phase–interface membrane, interface membrane–nonpolar phase and polar phase–electrode interactions. Further work involved investigations into the potential application of the assembled MnOx/MnOOH films as high performance supercapacitor
