Abstract:

Copper based sulfide-rich nanomaterials have recently attracted attentions in various applications due to inexpensive, abundance and non-toxicity of their constituent elements. Cu4SnS4 and CuCo2S4 as the members of this family have exhibited good capability with a stable manner in solar cells, energy storage electrodes, batteries, etc. In this work, through a facile and rapid combustion reaction accelerated by microwave irradiation, Cu4SnS4/CuCo2S4 nanoparticles was prepared. Thiourea was used as a sulphur source and also organic driving agent. The features of the synthesized product were studied using fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersion of x-ray spectrometry (EDX) techniques. The FT-IR and XRD results showed the formation of a multi-components structure containing orthorhombic crystal phase of Cu4SnS4 alongside carrollite CuCo2S4 phase. Some electrochemical properties of the as-prepared nanomaterial was investigated by performing cyclic voltammetry (CV) tests in different electrolytes.
