Investigation of MnO2/MWCNTs nanocomposite for various applications
The MnO2/Multi-walled carbon nanotubes (MC) nanocomposite was prepared by one-pot facile synthesis process. Potassium permanganate (2.5 g), concentrated sulphuric acid (0.5 ml) were used as precursor for preparing MnO2 and Multi-walled carbon nanotubes (MWCNTs-100 mg) was added to it and stirred at...

| Summary: | The MnO2/Multi-walled carbon nanotubes (MC) nanocomposite was prepared by one-pot facile synthesis process. Potassium permanganate (2.5 g), concentrated sulphuric acid (0.5 ml) were used as precursor for preparing MnO2 and Multi-walled carbon nanotubes (MWCNTs-100 mg) was added to it and stirred at 70°C for 1 h to produce the nanocomposite. The prepared nanocomposite was studied by transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy, UV–visible (UV) spectroscopy and thermal analysis. The electrochemical behaviour of prepared nanocomposite was examined by cyclic voltammetry (CV) and impedance spectroscopy. The magnetic property at room temperature (RT) was investigated using vibrating sample magnetometry (VSM). The antibacterial activity was studied against S.aureus and E.coli bacteria. The morphology revealed that, MWCNTs were decorated by cross-linked MnO2 nanoflakes uniformly. The nanocomposite exhibited increased bandgap, enhanced thermal stability, higher specific capacitance, ferromagnetic behaviour (at RT) and improved antibacterial activities. |
