MnO2 and banana peel derived porous carbon composites for high performance supercapacitors |
| 초록 |
MnO2/biomass-derived porous carbon (BPC) composites have been prepared by a hydrothermal method, in which the BPC 3D porous carbon structure was based on a banana peel. The banana peel provides enough growth space for MnO2 and reduces the agglomeration of MnO2 particles. The electrochemical performance of the composites was tested in three-electrode supercapacitors using 1 M Na2SO4 aqueous solution as an electrolyte. Due to the large amounts of hierarchical pores and large pore volume, the as-prepared composites exhibited good electrochemical performance. Electrochemical measurements indicated that the MnO2/BPC composites applied in supercapacitors had a specific capacitance of 139.6 F g-1 at 300 mA g-1, and exhibited a good cycling stability with a capacitance retention ratio of 92.3% after 1000 cycles (at 1 A g-1). The MnO2/BPC composites with 3D porous structure are promising materials in the application of supercapacitors. |
