Abstract

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.
