【 摘 要 】

References(20)Cited-By(4)Sub-micron sized hollow spheres were fabricated starting from core-shell particles. Polystyrene particles with a size of 345 nm were coated with a titania shell of 15 nm thickness by a sol-gel method. The core-shell particles prepared were annealed at 500°C in air to remove the polystyrene core and crystallize the titania shell. The crystal structure of the hollow titania shell was anatase and its surface area was 91.0 m2/g.
