Effect shapes of nanorods, nanowires and nanobelts TiO2 on the degradation of MB photo catalyst.

Abstract

Titanium dioxide (TiO2) was prepared using hydrothermal method. The crystallite structure was characterized by X-ray diffraction (XRD), which showed the TiO2 have two phases anatase and rutile. Field-emission scanning electron microscopy (FE-SEM) used to investigate the morphology of TiO2, such the images showed that the product have nanorods hexagonal, nanobelts, and nanowires. The different shapes of nanotitanum dioxide on Photocatalyst were studied on degradation of methylene blue dye under UV irradiation, optimum degradation revealed with nanowires shape compare with nanobelts and nanorod shapes.
