In this study, graphitic carbon nitride (g-C3N4) was made by thermal condensation of melamine at 450 and 550 °C. Moreover, the TiO2 porous nanostructured electrode was fabricated as a substrate for the g-C3N4 deposition by anodization method on a titanium foil (Ti) and then, reduced by electrochemical method to improve electrical conductivity (Re-TiO2 NP). The graphite carbon nitride layers were deposited on the porous nanostructured electrode (Re-TiO2 NP/Ti) by electrophoretic technique and the g-C3N4/Re-TiO2 NP/Ti electrodes were used as supercapacitor electrode. Comparison of the supercapacitive properties of the g-C3N4/Re-TiO2 NP/Ti electrodes showed that the electrochemical efficiency and specific capacitance of the g-C3N4 (450)/Re-TiO2 NP/Ti electrode is higher than the g-C3N4 (550)/Re-TiO2 NP/Ti electrode due to the increased active sites and charge transfer and the enhanced hydrophilicity as result of its high nitrogen content.
