Synthesis of PbS Nanocrystals by Heterogeneous Reaction

Abstract:

PbS nanocrystals was synthesized by a heterogeneous reaction of hydrogen sulfide gas and lead nitrate solution containing EDTA in ethanol. The influenceof initial molar concentration ratio of EDTA/Pb (NO₃)₂ (C_EDTA/C_{Pb (NO3)2}), volume ratio of ethanol/water (V_ethanol/V_H2O), pH value and flux of H₂S on the particle size of PbS were investigated. The structure, morphology, particle size, and particle size distribution ranges of PbS were characterized by XRD, FE-SEM, and laser particle size analyzer, respectively. Increasing C_EDTA/C_{Pb (NO3)2}, V_ethanol/V_H2O, and pH value, as well as decreasing the flux of H₂S decrease the particle size of PbS. PbS nanocrystals have an average particle size of 69 nm, a narrow size distribution, and a quasi-spherical shape when C_EDTA/C_{Pb (NO3)2} is 1, V_ethanol/V_H2O is 1, pH is 3.5, and the flux of H₂S is 20 ml/min.
