| Summary: | In recent years, ZnO, Sn02 nanostructures have received special attention of researchers due to their
potential in commercial applications. ZnO and Sn02 mixed materials are promising materials for several
applications such as gas sensing and optoelectronic devices 1. Many methods have been introduced for the
fabrication of mixed metal oxide nanostructuresi". Most of them involve multiple processing steps which
results a core-shell or hierarchical nanostructures. In this work, ZnO-Sn02 mixed nanostructures were
sYnthesized by a single-step carbothermal reduction method by vapor liquid solid mechanism. The Morphology
and crystal structure of fabricated mixed nanostructures were characterized by field emission scanning electron
~icroscope (FESEM), transmission electron microscope (TEM) and X-ray diffraction (XRD). XRD results
Indicated that the ZnO-Sn02 mixed nanostructures possessed crystalline structure. FESEM images revealed the uniform nanowires with diameter ranges from 15 nm to 80 nm and length of several tens of micrometers. The
distribution of elemental Zn and Sn were found in mixed form in the nanowire which was confirmed by
elemental mapping of TEM images. These ZnO-Sn02 nanostructures can be employed in chemical sensing,
photovoltaic and photocatalysis applications. |
