1D CdS/PbS heterostructured nanowire synthesis using cation exchange

Abstract

Heterostructured CdS nanowires with PbS deposits forming p–n junctions have been synthesized by successive cation exchange. The method developed herein opens up the possibility of preparing a spatially distributed heterojunction-based multifunctional electrode. The (photo)electrochemical activity of the material may be chemically tuned by changing the size and density of the p type PbS nanoparticles.
