Abstract

In this work, combustion-synthesized $TiO_2$ nanoparticles were used for the photocatalytic degradation of methylene blue with UV light irradiation. Also the results were compared with those of commercial $TiO_2$ nanoparticles (Degussa, P-25). Particle characteristics of the two were analyzed thru the SEM, TEM, and XRD. In spite of the lower specific surface area than that of P-25, the $TiO_2$ nanoparticles formed in this study showed the relatively good ability to degrade the concentration of the organics.
