| Abstract: | Colloidal carbon spheres with hydrophilic surface were synthesized using glucose as precursor by hydrothermal methods.Amorphous SiO_2,anatase TiO_2 and cassiterite SnO_2 hollow spheres were successfully prepared using colloidal carbon spheres as template in conjunciton with the sol-gel method.The hollow spherical structures could be confirmed by TEM and SEM.The BET surface area of hollow spheres were about 183.8 m~2/g,32.5m~2/g,and 74.3m~2/g,respectively. |
