Fabrication and improvement in the electrochemical performance of a 2D g-C3N4-based symmetric supercapacitor device

This work evaluates the possibility of employing 2-dimensional graphitic carbon nitride (2D g-C 3 N 4 ) to be utilized in supercapacitor applications as an anode material. Compared to traditional carbon-based materials, g-C 3 N 4 (CN) has various benefits, including a higher energy-density and rate-capability. Therefore, we investigated the performance of a CN-based supercapacitor synthesized using an efficient and cost-effective thermal polymerization method. X-ray diffraction (XRD), data investigation indicated hexagonal symmetry composed with space group P-6 m2, indicating CN with no discernible presence of any other phases. The XRD pattern was utilised to calculate the average crystallite size, which was…
