One-step electrosynthesis of MnO2/rGO nanocomposite and its enhanced electrochemical performance

We present a facile one-step electrochemical approach to generate MnO2/rGO nanocomposite from a mixture of Mn3O4 and graphene oxide (GO). The electrochemical conversion of Mn3O4 into MnO2 through potential cycling is expedited in the presence of GO while the GO is reduced into reduced graphene oxide...
