G. Thirumoorthi | B. Gnanavel

Abstract: The influence of copper (Cu) in determining Photocatalyticbehaviour of WO3 prepared by microwave irradiation technique (2.45GHZ, 180 W/10 min). It deals the synthesized oxygen deficient nano spherical like morphology by adopting a novel microwave irradiation technique action method with and without dopant (Cu). The powder XRD results confirmed the as prepared samples in both the cases to be orthorhombic phase (WO3?H2O) and the annealed samples (W17O47) were indexed as monoclinic structures. Microscopic observation clearly demonstrated the dopant in shaping surface morphology through formation of sheet like structure with the desired dimensions in length and width which served as building blocks for the formation of WO3 nanoparticles. The UV?Visible analysis indicated the band gap energies of the doped samples to be lighter than that of surfactant free samples. These observations suggest that the doped nanomaterials may be suitable for photo catalytic applications and the oxygen vacancy may be used to induce the changes in electrical properties.
