Hydrothermal Synthesis of Lead Sulphide Nanoparticles and their Electrochemical Sensing Property

Abstract

Lead sulphide nanoparticles was synthesized using hydrothermal method. The formed lead suplphide (PbS) nanoparticles were characterized by using FT-IR, XRD, FE-SEM and cyclic voltammetry. The electrochemical detection of pollutant (4-Nitrophenol) was carried out by coating the lead sulphide onto the glassy carbon electrode (GCE) by drop coating method. The electrocatalytic performance of the modified GCE electrode with 4-Nitrophenolwas better when compared with bare electrode.
