Hydrothermal synthesis of Bi2S3 nanoparticle as a prospective electrode for supercapacitor

Abstract

Calumnar basalt structure-based nanorods of Bi2S3 nanomaterial have been synthesized via hydrothermal processes. Through powder X-ray diffraction and Rietveld refinement analysis, the single phase and orthogonal structural nature of the Bi2S3 nanoparticle were confirmed, and the surface of the Bi2S3 nanoparticle was examined by a scanning electron microscope, which revealed that the nanoparticle has a pentagonal top surface and is a calumnar basalt nanorod type. For the measurement of the length and width of the nanorods, an image analysis tool has been employed, and the energy storage activities of this nanomaterial have been investigated by CV and GCD studies. It reveals that the specific capacitance of material through CV ranges from 3.20 to 5.28 farad /g, and concerning GCD it varies from 0.84 to 1.128 F/g Energy density 0.152–0.20 F/g V2, and the power density ranges from 109 to 1098 FV2/g. Stability attained at 0.237 volts and estimated capacitance 4.0117 mF identified with 0.8 R2 value from ESI study for this nanoparticle.
