| description | Mn<sub>3</sub>O<sub>4</sub> for supercapacitors was prepared by hydrothermal method at different reaction temperature and certain reaction time. Y doped and composite graphene were realized. The morph-ology, structure and electrochemical properties of the samples were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical workstation. The standard PDF cards 89-4837 are identical and the single phase Mn<sub>3</sub>O<sub>4</sub> belongs to tetragonal system. The space group is <i>I</i>41/<i>amd</i> (No. 141). The prepared Mn<sub>3</sub>O<sub>4</sub> is rod like particle. The specific capacitance of Y-Mn<sub>3</sub>O<sub>4</sub> and Y-Mn<sub>3</sub>O<sub>4</sub>/graphene composites can reach 89 F·g<sup>-1</sup> and 267 F·g<sup>-1</sup> when Y content is 5%. The cyclic voltammetry curves of Y-Mn<sub>3</sub>O<sub>4</sub>/graphene composites are rectangular, indicating that Y doped and graphene loading synergistically improve the electrochemical performance of Mn<sub>3</sub>O<sub>4</sub>. |
