Synthesis and Characterization of Bi2S3 Nanorods Decorated on Carbon Sphere and Study its Electrochemical Application

Bismuth sulfide(Bi2S3) nanorods(NRs) decorated on uniform shape carbon sphere(CS)have been prepared by hydrothermal method, using single source precursorpolyvinyl pyrrolidone(PVP) as a capping agent. The nanoparticles were synthesized with different ratio of capping agent at different temperatures.The prepared nanoparticles were characterized by FTIR spectroscopy,thermo gravimetric and differential thermal analysis. The crystallinity, morphology and elemental composition of the synthesized nanocrystals have been confirmed through X-ray diffraction (XRD), HRSEMand EDX. The electrochemical catalytic activity on the reduction of catechol of the synthesized Bi2S3 NRs has been investigated.The electrocatalytic oxidation of catechol done with Bi2S3NRs coated CS/GCE modified by using CV and the effect of the scan rate also studied. The modified nanocomposites Bi2S3NRs on CS in GCE are act as a good sensor by detection of catechol in ultra trace level by using DPV techniques.
