TL;DR: In this paper, a simple one-step anodic sonoelectrochemical method to synthesize PbS nanoparticles has been developed, with the lead foil as the sacrificing anode, and 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.
Abstract: 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.

TL;DR: IL/W was found to be the most suitable medium for the electropolymerization of MOT because the oxidation onset potential of MOT in IL/W microemulsions was lower than that in micellar aqueous solutions or conventional organic solvents.

TL;DR: In this paper, the steady-state limiting current for reduction of mono and divalent metal cations to amalgam in solution without supporting electrolyte was found to agree well with theoretical predictions (for reduction of M +, 2 and 3/2 for X - and X 2-, respectively).
Abstract: The steady-state limiting current for reduction of mono and divalent metal cations to amalgam in solution without supporting electrolyte depends on both the charge of the cation and the charge of the associated anion. The ratio of limiting current in the absence of supporting electrolyte (i i o ) to diffusional current (i d ) was found to agree well with theoretical predictions (for reduction of M + , 2 and 3/2 for X - and X 2- , respectively, and for M 2+ , 3 and 2 for X - and X 2- , respectively). The reduction current of metal cation depends on the type and concentration of supporting electrolyte. The diffusional current is reached at a lower electrolyte ratio when the cation of the electrolyte is divalent than when it is monovalent in solutions without supporting electrolyte, the limiting current for reduction of a cation having a large negative reduction potential was found to increase in the presence of a cation reducing at a less negative potential. This phenomenon was observed for thallium ion with hydrogen ion and for lead ion with hydrogen ion. The increase of the current is due to the increased rate of transport of the more easily reduced cation at potentials where both reductions are transport-controlled
