High edge energy storage with large life-span stable materials have become the most significant and major requirement in near future. Bismuth sulfide (Bi 2 S 3 ) nanoparticles (NPs) was effectively synthesized by utilizing bismuth diethyldithiocarbamate (Bi[DTC] 3 ) complex as single-source antecedent. The synthesized Bi 2 S 3 NPs were affirmed by structural, morphological and thermal analysis with various analytical studies. The electrochemical performance of Bi 2 S 3 NPs reveals that, exhibit redox behavior from cyclic voltammetry analysis, the charge–discharge analysis was examined by the galvanostatic chronopotentiometry. Bi 2 S 3 NPs exhibit excellent supercapacitor behavior with value of the specific capacitance 470 Fg −1 at current density 0.5 Ag −1 and the retentivity of 79% after 1000 cycles. The Bi 2 S 3 NPs were further utilized as photocatalytic discoloration of Congo Red (CR) dye in aqueous medium under UV light irradiation. Which shows, excellent catalytic behaviour, up to 98% of CR dye degrade within 150 min and it is exhibit good catalytic stability and reusability.
