 Abstract
In this study, novel sensitized nanocomposites were prepared by facile sonochemical assisted synthesis method. The as-prepared products were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM) with energy dispersive X-ray (EDX) analysis, transmission electron microscopy (TEM), and N2 adsorption BET analysis. The as-prepared nanocomposites simultaneously possessed great adsorptivity for organic dyes and efficient charge separation properties. In the decolorization of rhodamine B, a significant enhancement in the reaction rate was observed for the nanocomposite compared to the cases of using pure P25 or . The sonocatalysis activity was higher due to the greater formation of reactive radicals, as well as to the increase of the active surface area of the nanocomposite.
