The mechanism of PbSe electrodeposition from aqueous solutions contain
ing Se-IV and Pb-II have been investigated. It has been found that PbS
e formation is possible at potentials more positive than the Nernst po
tential EPb2+/Pb0. In this case the electrodeposition of PbSe is due t
o chemical interaction between overpotentially deposited selenium and
underpotentially deposited lead adatoms. (C) 1997 Elsevier Science Ltd
