| Popis: | A novel method for the fabrication of tetrasulfanilamide cobalt(II) phthalocyanine (CoTSPC) was developed and the synthesized product was characterized using various techniques namely UV-visible, infrared and X-ray diffraction spectroscopic and thermal gravimetric analysis. An electrode with glassy carbon was modified on CoTSPC with an rGO composite. The effect of experimental parameters, such as precipitation agent, precursor concentration, reaction time and stabilizing agent, was systematically studied to investigate possible CoTSPC formation. The electrochemical properties of prepared CoTSPC/rGO/GCE were explored through cyclic voltammetry (CV) by using a three-electrode system. The results showed that the specific capacitances and sizes of the fabricated compounds are related. Due to a large surface area, within an operated voltage range of −0.2 to 0.4 V, synthesized CoTSPC/rGO/GCE exhibited an excellent long-cycle life and the highest capacitance (157 F g−1), thereby indicating that fabricated CoTSPC/rGO/GCE can be used as an outstanding electrode material in supercapacitors. |
