Abstract
- Abstract: Amorphous SiO2, anatase TiO2 and cassiterite SnO2 hollow spheres have been successfully prepared using hydrophilic colloidal carbon spheres as template in conjunction with the sol–gel method. The hollow spherical structures could be confirmed by TEM and SEM. The void sizes of these hollow spheres were about 60% smaller than the diameters of the template. The BET surface areas of hollow spheres were about 183.8, 32.5, and 74.3 m2/g, respectively. [Copyright &y& Elsevier]
