Controlled Synthesis of Trimanganese tetroxide nanorods: Applications on electrochemical supercapacitors |
| 초록 |
This paper reports on a controlled solution processed synthesis of trimanganese tetraoxide (Mn3O4) nanorods (NRs) using potassium permanganate KMnO4, as precursor at low temperature of 80oC. It was found that the pH and reaction time were crucial for achieving the rods like morphology. pH 12 and 24 h were found to be the optimum conditions for the formation of Mn3O4 NRs. With crystalline and structural studies, the characteristic tetragonal spinel structure of Mn3O4 NRs was confirmed wherein the divalent manganese ions were attached in the tetrahedral coordination. The band gap of Mn3O4 NRs was estimated to be 2.43 eV which was slightly higher than Mn3O4 nanoparticles (NPs) due to the transformation of NPs to NRs morphology. The synthesized Mn3O4 NRs were used as electro-active materials for electrochemical supercapacitors and showed reasonably high specific capacitance of 266 F/g at 10 mV/s due to its excellent electrochemical behaviour. |
