Preparation and Characterization of Nanoparticles TiO2 and Its Application for Methylene Blue Dye Degradation under Solar Light

Abstract

This research paper study, the treatment of m ethylene blue dye was investigated in a photo catalytic
system under solar irradiation in heterogeneous solution with multi concentrations like (0.3 , 0.8 , 1.3 ,
and 2) g/l of commercial TiO2 as a photo catalyst. The optimum value of photo catalyst concentration (0.8
mg/l) the nano particles TiO2 was prepared by using sol-gel technique. The properties of the prepared
TiO2 were checked with X-ray and transmission electron microscopy technique. Then the treatment of
the m ethylene blue dye was checked by using synthesis TiO2with same previous conditions. We have
compared the treatment efficiency of solution between the prepared nanoparticles and commercial TiO2.
The results shows that the prepared TiO2hasa more efficiency. The practical work also includes the
recycled ofTiO2 nano particles.
