TiO2 is one of the common materials used for solar cells, diodes, different types of gas sensors, optoelectronic devices, etc., TiO2 is widely used in photovoltaic devices due to interesting optical and electrical properties. In this research, there are different types of nano materials were synthesized by different methods, Firstly, TiO2 nanoparticle has been prepared by sol-gel techniqu. Secondly, TiO2 nanord and TiO2 nanowire were synthesized by a hydrothermal method. The thin films of these samples (TiO2 NPs-TiO2 NRAs-TiO2 NWAs) were synthesized on glass substrates via. doctor-blending method. The as-prepared samples were characterized by x-ray diffraction, HR-TEM, FE-SEM and UV-Visible spectrophotometer. X-ray diffraction pattern showed the phase structures of these samples, the Scanning Electron Microscopy (SEM) is used for analysis of morphology and Ultraviolet Visible spectroscopy (UV-Vis) was used to get the degradation degree, the light intensity and the optical absorbance.
