چکیده انگلیسی
Anatase titania hollow spheres were prepared using hydrothermally prepared carbon spheres as template. The prepared hollow spheres were characterized by XRD, BET, TEM, XPS and diffuse reflectance spectrum (DRS). The photocatalytic activity of the as-prepared titania hollow spheres was determined by degradation of MB in aqueous solution, and was compared to commercial P25 titania. It was revealed that the photocatalytic activity of the titania hollow spheres enhanced a lot. The apparent rate constant of the titania hollow spheres is almost 6 times as that of P25 titania.
