Description
Summary:Recently, Exfoliated graphitic carbon nitride (E-gCN) has drawn significant interest in the field of energy generation and storage. In this study, exfoliated graphitic carbon nitride nanoflakes are synthesized by condensation followed by ultrasonic exfoliation. The supercapative behavior of exfoliated graphitic carbon nitride is analyzed. Structural analyses confirm the formation of thiazine and heptazine heterocycles. Scanning electron microscopy image shows flake-like morphology. The E-gCN exhibit the specific capacitance of 160 F g −1 at 1 A g −1 and retains 96.2% capacity at 3000 cycles. The presence of nitrogen in the two-dimensional layered structure significantly increases the conductivity and alters the electronic structure. The nano-flake morphology increases the charge diffusion kinetics, which improve the charge storage mechanism.
