Tri metal sulphide diethyl dithiocarbamate complex [Sb₂S₃: MnS: Cu_7.2 S₄ (DDTC)], empowered with effective optoelectronic and supercapacitive nature

The goal of this research work is to carry out a complete investigation of fabrication and characterization of tri metal sulphides [Sb₂S₃: MnS: Cu_7.2S₄ (DDTC)] complex compound. In this synthesis, diethyl dithiocarbamate was employed as a single source precursor. The materials’ internal composition, surface appearance and light-dependent features were studied utilizing a range of analytical methods to gain insight into their properties. With an 81.35% crystallinity and an 11.79 nm crystallite size of tri-metallic sulphide material, the XRD investigation showed well defined crystalline composition. Materials containing tri metal sulphides were shown to have an arrangement of morphological particles via SEM pictures. The material’s low bandgap energy of 2.17 eV was discovered by analyzing its optical characteristics using UV–visible spectroscopy. FTIR results verified the excellent metal-sulphide bonding making it a good electroactive material. Electrochemical research employing voltammetry measurements revealed that these trimetal sulphide materials performed exceptionally well with current density of 76.43 mA/cm² at electrodes in LSV. The remarkable specific capacitance of 364 F/g was observed in CV data. GCD data revealed an effective specific power density of 1341W/kg. Whereas the EIS study demonstrated a relatively low series resistance of Rs = 0.56 Ω. The advantageous electrochemical capabilities of tri metal sulphides for photoelectric and electrochemical devices like solar cells and supercapacitors were confirmed by these electro-analytical results.
