Photocataltic activity of Zr-doped TiO2 on organic compounds

Doped-TiO2 nanocrystalline powders (nM:TiO2:Zr) with anatase structure .we have focused on the production of different nanostructured Zr modified TiO2 powders as a material for photocatalytic by sol gel assist- polymerizing complexing combustion method (PCCM) and hydrothermal method and characterized by SEM Analysis, UV-VIS anylsis, XRD Analysis Of Zr Modified TiO2 particles, XRD Analysis Of TiO2 and 5 % ZrO2-TiO, XPS Anlysis Of Zr Modified TiO2 particules, XPS Anlysis Of 5%Zr-TiO2 particules .Results revealed that the anatase structure is highly stable for all doped TiO2 prepared compounds with enhancement in the surface area. UV-Vis diffuse reflectance spectra showed that these dopants were responsible for narrowing the band gap of TiO2 and shifting its optical response from ultraviolet to visible-light region. The photocatalytic activities of Zr-doped TiO2 catalysts were investigated with testingwith these materials (Methylene Blue (MB) Test, Purple Dye (PD) Test, Methly Orange (MO) Test and Malecite Green (MG) Test ) . all experiments were done with the help of a xenon lantern to simulate the sun's rays., it was found that The results of the obtained tests have a longer duration than the results in the literature made with UV, they are very important in terms of cost analysis and practical use. the resulting disintegration rates are still faster than the best alternative methods. for this reason a great obstacle for the commercialization of the particle has come to an end.
