Abstract

In this work, size and morphology controlled novel tungsten oxide nanospheres have been synthesized via ureaassisted solution combustion method. Urea played the role of a fuel in the combustion process. The prepared WO3 nanospheres were characterized by different methods. X-ray diffraction analysis indicated that the particles were fine crystallised in the nanorange with amonoclinic phase pure crystalline structure. The field emission scanning electron microscopy images confirmed the nanospheres like morphology of WO3 particles with high agglomeration tendency. Grain size of the nanospheres was noted to be almost same (10-20 nm) when the preparation was done with urea, whereas the size control is found to be diminished in the absence of urea. Adsorption and photodegradation of methylene blue was investigated over the WO3 nanospheres under visible light, indicating the potential role of WO3 nanospheres for the permanent removal of dyes from waste water.
