Utilization of Carbon Nanospheres in Photocatalyst Production: From Composites to Highly Active Hollow Structures.

ABSTRACT: Titanium dioxide-carbon sphere (TiO₂-CS) composites were constructed via using prefabricated carbon spheres as templates. By the removal of template from the TiO₂-CS, TiO₂ hollow structures (HS) were synthesized. The CS templates were prepared by the hydrothermal treatment of ordinary table sugar (sucrose). TiO₂-HSs were obtained by removing CSs with calcination. Our own sensitized TiO₂ was used for coating the CSs. The structure of the CSs, TiO₂-CS composites, and TiO₂-HSs were characterized by scanning electron microscopy (SEM), infrared spectroscopy (IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and diffuse reflectance spectroscopy (DRS). The effect of various synthesis parameters (purif
