| Summary: | MnO is an attractive material due to its high specific capacitance and thermal and chemical activity. It can be recycled from alkaline batteries with a good yield and can be used for supercapacitor applications after enhancing its poor conductivity. In this study, Ru-MnO-Carbon nanofibers(Ru-MnO-CNFs) were prepared by the impregnation of Ru (1 wt%) into MnO recovered from used alkaline batteries, followed by their incorporation into polyacrylnitrile (PAN) nanofibers by electrospinning and carbonization. The prepared materials, Ru-MnO and Ru-MnO-CNFs, were characterized by scanning electron microscopy and Fourier infrared spectroscopy. The electrochemical characterization was performed, comparing the characteristics of Ru-MnO and Ru-MnO-CNFs samples. It was found that the capacitance of MnO recovered from used alkaline batteries could be enhanced by combining it with Ru and CNFs. The hybrid Ru-MnO/CNFs composite could be used as stable electrode material for high performance supercapacitors. |
