Improvement of Photocatalytic Properties of Titanium Oxide Nanoparticles (TiO2) Doped with Cerium Atoms and Evaluation of Methylene Blue Dye and Wastewater antifreeze Treatment

In this study, the photocatalytic and bleaching properties of pure and doped titanium dioxide nanoparticles with 1%, 3%, 5% and 10% Ce dopant were studied using Ce(NO3)3 precursor. The results showed that the highest methylene blue degradation of the sample with 5% cerium impurity was 97% in neutral medium (pH=7) after 75 minutes. The bleaching response to wastewater treatment with 5% cerium impurity was 80% at wavelength of 490 nm.
