Structural and electrochemical properties of single crystalline MoV2O8 nanowires for energy storage devices

We report the synthesis of MoV2O8 nanowires of high quality using spin coating followed by the thermal annealing process. Transmission electron microscopy (TEM) reveals the average diameter of synthesized nanowire about 100 nm, and average length ranges from 1 to 5 μm. The TEM analysis further confirms the <001> growth direction of MoV2O8 nanowires. The electrochemical properties of synthesized nanowires using cyclic voltammetry show the specific capacitance 56 Fg−1 at the scan rate of 5 mV s−1 that remains 24 Fg−1 at 100 mV s−1. The electrochemical measurements suggest that the MoV2O8 nanowires can be used as a material for the future electrochemical capacitors (energy storage devices).

MoV2O8 nanowires were synthesized, characterized and their electrochemical behavior for the applications as energy storage devices such as supercapacitors was investigated successfully.Figure optionsDownload as PowerPoint slideHighlights
