High edge energy storage with large life-span stable materials have become the most significant and major requirement in near future. Bismuth sulfide (Bi2S3) Nanoparticles (NPs) was effectively synthesized by utilizing Bismuth diethyldithiocarbamate (Bi[DTC]) complex as single-source antecedent. The synthesized Bi2S3 NPs were affirmed by structural, morphological and thermal analysis with various analytical studies. The electrochemical performance of Bi2S3 NPs reveals that, exhibit redox behavior from cyclic voltammetry analysis, the charge-discharge analysis was examined by the galvanostatic chronopotentiometry. Bi2S3 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 Bi2S3 NPs were further utilized as 2 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.

High-performance energy storage electrode materials are emerging demand in near future for the construction of supercapacitor with high energy and power densities. Herein, Nickel (II) Diethyldithiocarbamate was used as single source precursor for Nickel Sulfide (Ni9S8) two dimensional (2D) nanosheets preparation and hexadecylamine as shape directing agent via simple solvothermal method. The orthorhombic structure of Ni9S8 nanosheets was confirmed by X-ray diffraction (XRD) pattern. Scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM) images revealed that as-prepared Ni9S8 nanoparticles possess sheet-like morphology. Besides, the thermal stability of Ni(DTC)2 complex was studied by Thermo-gravimetric/Derivative thermo gravimetric(TG/DTG) with Differential scanning calorimetric (DSC) analysis. The electrochemical properties of Ni9S8 nanosheets was studied using galvanostatic charge-discharge (GCD) and cyclic voltammetry (CV) techniques. From the charge-discharge study of Ni9S8 nanosheets, a high specific capacitance of 281 Fg− 1 was obtained at a current density of 1 Ag− 1, and up to 82 % retentivity was achieved after 5000 cycles. Thus, the prepared Ni9S8 nanosheets could be one of the attractive potential active electrode materials for the application of supercapacitor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
