Titania/polymer capsules and hollow titania spheres are prepared by using sulfonated-polystyrene core–shell gel particles as templates. The titania shell thickness and the cavity size are controlled in the entire particle radius range. If an electric field is applied during synthesis, hollow spheres with pillared surfaces (depicted) are produced.
