In this research, a one pot simple, solid state and rapid combustion method assisted by microwave irradiation with a power of 900 W for 20 min was used to synthesize CuCo2S4 nanoparticles and heterogeneous CuCo2S4 / g-C3N4 nanocomposite, Thioacetamide was used as a sulfide source in the synthesis of the ternary chalcogenide CuCo2S4 and its composite with g-C3N4. In addition, graphitic carbon nitride (g-C3N4) at the nanoscale was also prepared by the same method 20 min using thiourea as a carbon and nitrogen-rich precursor. The study of structural and morphological characteristics of the prepared products using X-ray diffraction spectroscopy (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), Diffuse reflection spectroscopy (DRS) and X-ray energy diffraction spectroscopy (EDX), revealed the formation of nanoparticles with the average size in the range of 20-40 nm. Furthermore, the electrochemical properties of the resulting products as an electrode material were investigated by performing cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) tests. The CV tests results showed special capacitances of 320 F.g-1, 202 F.g-1 and 428 F.g-1 in respective for CuCo2S4, g-C3N4 and CuCo2S4 / g-C3N4, introducing them as suitable candidates for use in energy storage devices. The employed synthesis method can provide a new, easy, rapid and environmentally friendly way to produce various nanomaterials and nanocomposites for different applications.
