Effect of Calcination Temperature on Structural Properties and Photocatalytic Activity of Ceria Nanoparticles Synthesized Employing Chitosan as Template

الملخص EN

Ceria nanoparticles were synthesized employing chitosan as template and thermal treatment at different temperatures (350, 650, and 960°C).

The effect of calcination temperature on structural properties and photocatalytic activity of ceria nanopowder was also tested.

Degradation of an azo dye, Congo Red (CR) as a model aqueous pollutant, was investigated by means of photocatalysis of ceria nanoparticles under visible light irradiation.

The influence of catalyst amount, initial CR concentrations, and degradation reaction kinetics were studied.

The results were compared with commercial CeO2 at the same degradation conditions.
