Organic–inorganic hybrid hollow spheres are prepared by using a TiO 2‐stabilized
Pickering emulsion polymerization method (see figure). By self‐organization of TiO 2
nanoparticles at the interface of oil (monomer and solvent) and water, colloidosomes are
formed and used as polymerization vessels to obtain the hybrid hollow spheres. The
diameter and mechanical stability can be tailored by varying the relative amount of oil phase
and the relative amount of divinylbenzene (DVB) in the monomer, respectively.
