PbS Nanoparticle Sensitized ZnO Nanowire Arrays to Enhance Photocurrent for Water Splitting
Improving
the visible-light absorption is one of the key ways to
optimize the photoelectrochemical performance of zinc oxide (ZnO)
nanowire arrays (NWs). In this study, as-synthesized PbS nanoparticles
(NPs), which are adsorbed onto ZnO NWs through a dip-coating method,
are used to enhance the photocurrent of the ZnO NW photoelectrochemical
anode for water splitting. The morphology crystalline nature and optical
properties of the ZnO NWs and PbS nanoparticles (NPs) were characterized
by TEM, HRTEM, XRD, and UV-NIR absorption spectra. The hybrid anode
exhibits a significant photocurrent density enhancement which is about
ten times larger than that of pristine ZnO NWs. Moreover, we believe
through some effective modifications there is ample room for improvement
of the photoelectrochemical performance of the PbS NP sensitized ZnO
NW photoanode that can be achieved
