Abstract
Layer structured carbon materials are widely used in energy storage applications because of their good conductivity and large surface area. Layered porous g-C3N4 is a promising energy storage material due to its specific properties of high charge mobility, mechanical stability and wettability. In order to overcome the low specific capacitance and low conductivity of g-C3N4, it was doped with the highly conductive Vanadyl phosphate (VP) by the hydrothermal method. The different synthesized materials were characterised using UV−Vis-DRS spectroscopy, Fourier transform infra red spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy techniques (TEM) and energy dispersive x-ray spectroscopy (EDS). The electrochemical investigation was carried out by cyclic voltammetery (CV), Galvanostatic charge discharge (GCD) and electrochemical impedance spectroscopy (EIS) studies. The synthesized C3N4/VP composite material exhibited excellent capacity value of 498 Cg−1 and also showed a good cyclic stability up to 5000 cycles of charge discharge, when compared to the individual materials g-C3N4and VP. The entire study clearly shows that the Vanadium based composite is a powerful storage material which has a great scope to be used for future energy needs.
