Selectively Nanocubes Formation of Tungsten Oxide (WO3)

Abstract

In this study, tungsten oxide (WO3) nanoparticles were produced with a preferential nanocube morphology by using selenium (Se) and lanthanum (La) catalysts in de-ionized water by arc discharge method. Se-La catalysts were added to the tungsten (W) electrodes during the production of nanocubes and the structural and morphological features of these nanocubes were investigated. The nanocube structures were imaged with scanning electron microscopy (SEM) and permeable electron microscopy (TEM), and the dimensions of the nanocubes were between 10-50 nm. X-ray diffraction (XRD) results revealed that the synthesized nanostructures exhibited a monoclinic WO3 crystal structure. The arc discharge is a simple, inexpensive and low-cost method and the production of WO3 nanocubes at a high purity rate has been successfully achieved with this method.
