Thermal effects for the doped graphene quantum dots: Cyclic voltammetry

With an objective to develop electrode materials with high specific capacitance and good stability, we prepared Graphene quantum dot-doped transition metal of HCl by using a facile hydrothermal at different temperatures (~ 800C- 1400C). Samples were characterized Raman spectroscopy, Powdered X-ray Diffraction (PXRD), U-V Visible Spectroscopy, Transmission Electron Spectroscopy (TEM). spectroscopy study reveals intensity ratio alters changes in temperatures. It was found the variation size doped GQDs under temperature conditions from TEM measurements. The observed blue shifts energy gap higher are attributed strong interaction HCl. Electrochemical studies showed superior strategy for generating metals GQDs. electrochemical activity has been originated cyclic voltammetry 1200C is be electrodes than all other heated samples. simplicity synthesized material suggests understand charge storage mechanism commercial applications.
