Abstract
Herein, a hydrothermal method was used for the synthesis of V 2 O 5 nanowires (NWs) and Ag-doped V 2 O 5 . The prepared doped material was intercalated in MXene for the preparation of an Ag-doped V 2 O 5 /MXene nanocomposite using a facile ultrasonication method. For structural and morphological confirmation, X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Fourier transform infrared (FT-IR) spectroscopy were used. Additionally, for electrochemical measurements, cyclic voltammetry (CV), cyclic-charge discharge (CCD), and electrochemical impedance spectroscopy (EIS) were performed. To avoid the restacking of Al-etched layers of MXene, Ag–V 2 O 5 nanowires were intercalated. This strategy ultimately increases the conductive channels, which helps in boosting the electrochemical properties of Ag–V 2 O 5 nanowires. To fabricate electrodes, indium tin oxide (ITO) was used as a substrate. As prepared, the Ag-doped V 2 O 5 /MXene@ITO electrode showed a significant increase in the specific capacity. For the Ag-doped V 2 O 5 /MXene@ITO electrode, the calculated specific capacitance was 875 F/g (at 1 A/g) using galvanostatic charge-discharge (GCD) data. Also, it lost 6.1% of capacitance after the 3000th cycle. Results suggest that as-synthesized Ag–V 2 O 5 /MXene nanocomposite is a potential electrode material for energy storage.
