MnO2 nanoflower is prepared by electrochemical conversion of Mn3O4 obtained by heat treatment of spent zinc‒carbon batteries cathode powder. The heat treated and converted powders were characterized by TGA, XRD, FTIR, FESEM and TEM techniques. XRD analyses show formation of Mn3O4 and MnO2 phases for...
