A facile one-step hydrothermal method to produce α-MnO2/graphene sheet composites and its electrochemical properties

A composite of graphene sheet (GNS) supported by nanotube-like MnO2 nanocrystalline (α-MnO2/GNS composites) has been fabricated through a facile one-step hydrothermal method. The nanosized MnO2 particles were homogeneously distributed on GNS, which have been confirmed by transmission electron micros...
