Synthesis of WO 3 in nanoscale with the usage of sucrose ester microemulsion and CTAB micelle solution

Abstract

WO 3 nanoparticles were successfully prepared using first the low temperature hydrolysis method and second the chemical reaction method in water-in-oil sucrose ester microemulsion consisting of S1570, 1-butanol, tetradecane and aqueous phase. In this study WO 3 nanoparticles also were prepared using the CTAB micelle solution. The resultant WO 3 nanoparticles have been investigated with X-ray diffraction (XRD), transmission electron microscopy (TEM), variable pressure scanning electron microscope (SEM) equipped with energy dispersive X-ray analysis (EDX) and X-ray photoelectron spectroscopy (XPS). The shape and particles size of the resultant WO 3 nanoparticles from both methods in sucrose ester microemulsion show similar spherical shape and size range between 10 and 50 nm. The WO 3 nanoparticles prepared with the CTAB micelle solution show spherical shape with the size range average of 25–50 nm.
