الملخص الإنجليزي

Titanium dioxide nanorods (TNR) and nanotubes (TNT) were prepared by sol gel method using anodic aluminium oxide (AAO) membrane as template and calcined at 550°C.

The structural of TiO2 nanorods and nanotubes investigated by X-ray diffraction (XRD), the surface topography and the morphology of the samples were characterized by atomic force microscopy (AFM), and scanning electron microscopy (SEM).

The photocatalytic activity of the TiO2 nanostructures were evaluated by the photodegradation of methyl orange (MO) solution at different concentrations 10, 20 and 35 ppm under UV irradiation.

The crystallinity and anatase phase of the TiO2 nanorods and nanotubes are confirmed by XRD measurements.

Average diameter size of TiO2 nanorods and TiO2 nanotubes obtained from AFM histogram were 96.14, 132.34 nm respectively.

A high photocatalytic activity of TiOR2R nanostructures were obtained at the three different concentrations under UV irradiation.
