Abstract
TiO2 spherical particles were prepared using hydrothermal reaction at different temperatures of 110, 150 and 190℃ for 5 h. The TiO2 samples were characterized by BET, XRD and SEM analysis. Specific surface areas and particle sizes are in the range of 148 ~ 240 m2g-1 and 323 - 450 nm, composed of tiny nanoparticles with size of 5 ~ 7 nm. It was found that photocatalytic degradation of methylene blue is highly sensitive to particle sizes on the adsorption and photocatalysis.
