Zinc
oxide (ZnO) and Ag deposited ZnO (ZnO@Ag) core-shell nanorods produced
electrochemically on indium tin oxide coated glass (ITO) substrate for the
first time without any organic surfactants or high annealing temperature.
Nanorod films were synthesized two-step synthesis procedure. Firstly, ZnO
nanorods electrodeposited at low temperature, in second step, in situ
electrochemically etching of deposited ZnO nanorod was carried out.
Characterizations of electrochemically produced films have been carried by
using morphologic, spectroscopic and structural analysis methods by using X-ray
diffraction (XRD), scanning electron microscope (SEM), atomic force microscope
(AFM), fourier transform infrared spectroscopy (FTIR), Elemental mapping, UV-visible
diffuse absorption spectra and photoluminesance spectroscopy (PL). The photocatalytic performance of the obtained
films was determined by degradation of methylene blue and malachite green dyes
under UV light illumination. Methylene blue and malachite green dyes completely
degraded under UV light irradiation after 150 and 180 min, respectively. Also,
photoelectrochemical (PEC; water splitting) performances of the produced films
were investigated under dark conditions and UV light irradiation. The ZnO@Ag
core-shell nanorods exhibited higher photocatalytic and photoelectrochemical
performance in comparison with unmodified ZnO nanorods film. The nanorods grown
on the ITO substrates showed very good photocatalytic activity and became
reusable without significant loss of activity.
