Oxygen defects and formation of Ce³⁺affecting the photocatalytic performance of CeO₂nanoparticles

Here we report the photocatalytic activity of CeO2 nanoparticles. This is carried out with methyl orange as the reference pollutant. Annealing of ceria under vacuum generates oxygen deficient CeO2 nanoparticles with defects such as oxygen vacancies and formation of Ce3+. This is evident from the cha... View More
