โœฆ Synopsis

A simple one-step anodic sonoelectrochemical method to synthesize PbS nanoparticles has been developed. With the lead foil as the sacrificing anode, Pb(II) was anodically dissolved from the lead electrode into the aqueous solution of sodium sulfide, supporting electrolyte (potassium nitrate) and capping agent (PVA) at a constant potential, and then the produced Pb(II) reacted with the sulfide anion to form PbS nanoparticles under ultrasonic irradiation. The effects of the applied potential, capping agent and ultrasound in the formation of PbS nanoparticles are discussed, and the results suggest that the anodic sonoelectrochemical method may be a general and convenient way to prepare metal sulfide nanoparticles.

HgS and PbS nanoparticles of about 15 and 20 nm in size have been prepared by the sonochemical irradiation of an ethylenediamine solution of elemental S and mercury acetate or lead acetate under air. The nanoparticles are characterized using techniques such as transmission electron microscopy, X-ray
