摘要：
A one-step procedure to fabricate anatase crystalline titania hollow spheres was reported. Anatase-crystalline titania hollow spheres were directly fabricated in aqueous solution with peroxo-titanium complex (PTC) as precursor and polystyrene (PS) spheres as template. Compared with the traditionally template method, the surface coating, the template removal and the crystallization of the titania shell were simultaneously finished in a one-step process. Transmission electron microscope (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermogravimetric analysis (TGA) were used to characterize the as-prepared titania hollow spheres. A possible formation mechanism was also discussed.
